The rise of smart heating & home automation

Posted on May 23, 2019July 28, 2023 by rob.fullsend

Smart heating & home automation: 2000-2019

10 years ago, smart heating & home automation might have sounded like concepts from Back to the Future. But with more internet-connected devices than ever before, they are now realities which look set to stay.

Now, this might lead you to ask “where’s my jetpack?”. But IoT-connected smart devices could save you just as much time and effort in the long run. Albeit without quite as much fun.

Smart appliances, the IoT and connected living

The Internet of Things, or IoT, essentially refers to the collection of devices which are connected to the internet, functioning without user input in most scenarios. This connectivity allows devices to communicate with sensors, other devices and systems outside of the device.

Now you can control multiple factors of your building using smart services. Nest paved the way for smart heating controls with its smart thermostat, introduced in 2011. Smart thermostats attempt to save energy by sychronising the timing of heating and cooling with patterns of household occupancy.

Their precursors, programmable thermostats, typically resulted in higher energy use than simple ones. This was largely down to user error and the difficulty of programming. A smart thermostat aims to obviate the need for human interaction, simplifying the task of saving energy whilst maintaining an equitable temperature.

Since then, a plethora of devices have become available, covering every conceivable application.

Various products can integrate with your lighting & garage door, sense smoke & carbon monoxide or toggle your devices to create the impression that somebody is home. And of course, all these devices will eventually integrate together.

Advantages of home automation

Home automation enables users to save time and effort. It could also lead to savings by preventing mishaps. Such as the one I experienced at the age of 19 when, after living with some friends for a year, we realised we’d had the boiler set to “continuous” the whole time. No – the bill was not a pretty sight.

We ended up paying considerably more than the cost of a smart thermostat, which made us wish we’d had the foresight to buy one. Then again, having just turned 18, our money was spent on goods in liquid form only. A smart thermostat would have been unlikely to make the cut.

Smart appliances will enable users to complete their housework remotely, prepare the house for guests, maintain cleanliness and much more. The concept essentially allows any application that can be dreamt up. It enables devices – rather than users – to utilise all the technology at our disposal.

Iot: Risks & Threats

The IoT is not simply a case of turning your devices on and then riding off into the sunset, however. Security risks, which pose the biggest threat to smart appliance development, are inherent in some devices and difficult to conclusively prevent.

Besides the router, each IoT-enabled connected appliance is also at risk from hackers looking for firmware vulnerabilities to exploit. The more devices, the more points of vulnerability.

Artificial Intelligence and Machine Learning look set to drive a wave of secure advancements within the sector. AI will constantly probe, detect and learn from security logs, reacting to cyber threats faster than humans. Machine Learning could enable self-diagnosing smart appliances, which issue update notifications and security fixes when a firmware issue is detected.

The future of smart heating & home automation

With our modern taste for convenience, it seems inevitable that smart appliances and home automation will play an increasing part in our lives in the years to come. It is imperative that the security risks inherent are tackled, rather than simply talked down.

However, provided robust threat prevention methods can be implemented, the concepts look like being the first of a new technological paradigm.

Boiler Installation – How Much Should It Really Cost?

Posted on May 22, 2019February 9, 2024 by rob.fullsend

The cost of purchasing and installing a new boiler can vary enormously, even between boilers of the same type. Here, we look at what you should expect to pay for your new boiler to be installed, and the details of such.

Boiler installation is a complex task and should only be undertaken by a qualified, Gas Safe Registered engineer, so learn here about what you can expect to pay in the process.

The Cost of a New Boiler

A common question that we get is “How much is a new boiler?”. Depending on the type, a new boiler’s cost and installation can widely vary in price.

The average cost of a new boiler can range from £625-750 for a small domestic boiler, to £2,500 for premium domestic models, all the way up to £7.5k or 8.75k for a large commercial unit. New combi or system boilers are, as a rule, cheaper than conventional heat-only boilers.

The cost of getting a new boiler fitted can depend to some extent on the boiler you’re getting, as well as the installation location. A straight replacement in the same spot, for example, will cost far less to install than a completely new, different boiler in a different location. This is because new pipework will need to be fitted on top of any necessary modifications to the location itself.

Types of Boilers & Their Prices

Below, you will find some typical prices for various boiler replacement scenarios, do keep in mind this is a ball park figure and they can change depending on the current climate and inflation standards. Nonetheless, these example costs include boiler, labour, parts and VAT – and we’ve included a power flush as standard.

Conventional (heat only) boiler

Regular boilers are heat-only devices. The boiler provides the heating and a cylinder provides hot water. The scenarios below show costs for replacing a regular boiler in its existing location, and for installing a new regular boiler in a new location.

The cost of moving the boiler will depend on whether it will be in the same room or moved to another room. Both of these prices assume that the cylinder and other equipment not directly related to the boiler remain in the same place.

Replacing a heat-only boiler in the same location: £2,937 (2 days)
Replacing a heat-only boiler in a new location: £3437 (2.5 days)

Assumed mid-range boiler cost of £1000.

Combi Boiler

Combination boilers provide both heating and hot water via the boiler, with no need for a cylinder to perform this function. Usually, a combi boiler installation will consist of either replacing an existing combi boiler or replacing a conventional boiler and hot water cylinder together.

Replacing an existing combi boiler

Here, we show approximate costs for a new combi boiler in situ, and in a new location.

Replacing a combi boiler, same location: £2,937 (2 days)
Replacing a combi boiler, new location: £3,687 (2.5 days)
Replacing a regular boiler & hot water cylinder with combi boiler: £4,250 (3 days)

This kind of replacement might need extensive additional work to remove the cylinder and redirect pipes to the new boiler location.

Replacing a conventional boiler & tank with combi boiler: £4,062 (3 days)

Assumed mid-range boiler cost of £1125.

Side Note: Any combi boiler replacement needs to be Boiler Plus compliant. Boiler Plus, which came into effect in April 2018, sets out revised energy efficiency and technical requirements for any new or replacement gas boilers being fitted in England.

The scheme stipulates that timing and temperature controls are required in new or replacement combi boilers An additional energy efficiency measure is required, such as weather compensation, load compensation, Flue Gas Heat Recovery, or smart heating controls. Each compliance method can be tailor-made for the customer’s requirements.

System Boiler

System boilers use an unvented tank to provide hot water and provide heating. System boilers offer excellent performance and are suitable for buildings with multiple bathrooms in use.

Typical scenarios involve replacing an old system boiler in the same location, replacing a conventional boiler & vented cylinder with a system boiler & unvented hot water tank, and replacing a combi with a system boiler/unvented hot water tank (standard for property extensions).

Replacing a system boiler, retaining the unvented hot water tank: £2,875 (2 days)
Replacing a conventional boiler/hot water tank with system boiler/unvented hot water tank: £5,562 (3-4 days)
Replacing a combi boiler with system boiler/unvented hot water tank: £5812 (3-4 days)

Assumed mid-range boiler cost of £1062.

Back Boiler

Back boilers are no longer installed, so the costs we will go through here are for replacing a back boiler with a newer boiler. A conventional boiler can be installed, retaining the hot water tank, or a combi boiler can be installed without the tank.

Replacing a back boiler with a new heat-only boiler, retaining the hot water tank: £3,937 (3 days)
Replacing a back boiler and hot water tank with a new combi boiler: £4,312 (3 days)

Assumed mid-range boiler cost of £1062.

Frequently Asked Questions

Can I Install A Boiler Myself

It is strongly advised to hire a commercial boiler installation team to install your boiler. The installation of a boiler typically requires professional expertise and certification. This is because it is an incredibly complex process that involves not only the fitting of the boiler itself but also the connection to water, gas and electrical systems.

It is also critical to comply with building regulations and safety standards as there are significant safety risks including gas leaks, carbon monoxide poisoning, and potential damage to property.

Is It Worth Getting A New Boiler or Should I Stick To Repairs?

In the UK getting a new boiler is often ‘worth it’ for several reasons as new boilers are energy efficient this leads to lower bills and reduced emissions. They are also more reliable, requiring fewer repairs and maintenance saving you money in the long term.

Upgrading improves heating performance and can increase property value. The investment in a new commercial boiler installation can lead to more comfort, savings and higher resale value for homeowners.

How Often Should I Replace My Boiler

The typical lifespan of a boiler is around 10 to 15 years but the actual lifespan can vary depending on factors such as the type of boiler, its usage and how well it has been maintained. M&E maintenance can extend the lifespan of your systems significantly, look out for signs of wear and tear, increased noise, reduced heating performance and higher energy bills as it may be time to replace it. Regular commercial boiler servicing by a qualified engineer can help assess the condition of your boiler and determine if replacement is necessary.

Before You Go…

The cost of each boiler installation depends on the individual building, the existing setup and the new boiler’s specific requirements. Additional factors such as construction costs and individual access requirements can also further drive up expenses.

Expect to pay upwards of £1,250 in any circumstance, plus the cost of the boiler itself, and block out 2 or 3 days for the installation. For more information on how Kiasu Workforce can help you with commercial boiler installations, get in touch with us today.

How CHP services could save you money

Posted on May 15, 2019July 28, 2023 by rob.fullsend

CHP services

Combined heat and power (CHP), or cogeneration, is a more efficient way to supply heat & power to buildings, avoiding network losses and reducing emissions. CHP utilises the heat produced as part of generating energy, using it for – you might have guessed – heating. The term “CHP services” includes programming, maintenance and repair, and also fitting replacement parts.

CHP plants for the future

Ian Hopkins is a director of ENER-G Combined Power, which has delivered more than 50 CHP-led energy services contracts within the healthcare sector. Hopkins states that “the energy cost and carbon-saving benefits of combined heat and power are difficult to match where there is a large heating/cooling demand over extended periods”. For the past 30 years, ENER-G has designed and manufactured CHP systems at its global headquarters and R&D centre in Salford.

CHP – effectively an engine and alternator – allows organisations to control their own energy generation and use, and even make profits by selling the excess back to the National Grid. CHP is best suited to large properties or sites which use a lot of energy. Hospitals, schools, hotels and industrial businesses would all be well-advised to investigate the benefits of cogeneration.

CHP servicing and repair

CHP systems, like any other, can fall foul of maintenance issues stemming from heat, vibrations, moisture and leaks. Systems should be checked daily to ensure smooth operation, and inspected periodically by somebody qualified in CHP engineering.

Inspection and servicing typically includes checking battery condition, spark plugs, oil/air filters and engine oil itself, calibrating & adjusting valve settings and verifying emissions testing.

Regular CHP services will safeguard your finances against the outlay of repair bills and replacement costs, as well as ensure the system is working hard for your pocket. To invest in CHP and scrimp on servicing equates to throwing money down the drain. Conversely, the relatively low cost of regular servicing is likely to pay for itself in the savings – and earnings – you can make.

CHPQA Certification

To qualify for CHPQA (Combined Heat and Power Quality Assurance) Programme financial incentives, systems require performance monitoring. You will need to declare generated electricity, fuel consumption and heat output over a period of time, then again annually for renewal.

CHPQA certification opens up a range of benefits. These include Renewable Obligation Certificates, Renewable Heat Incentive, Carbon Price Floor (heat) relief, Climate Change Levy exemption (for directly supplied electricity), Enhanced Capital Allowances and preferential business rates.

In addition to the direct benefits of certification, monitoring your system’s performance will allow for early identification of any defects or potential efficiency gains. Fitting your system with sensors can monitor variables such as temperatures, pressures, flow rates, electricity/heat output & fuel consumption. This is essential for knowing its capabilities & performance inside out.

CHP services = Cost savings

“CHP’s efficiencies are built into the technology,” says Mr Newman. “It is well-established as a technology, with multiple suppliers that ensure competitive pricing. That in turn equates to better overall client benefits.”

Providing you service your CHP system regularly using qualified CHP specialists, it is likely to prove a smart, efficient investment for years to come in helping you save money.

5 signs you need a new boiler installed

Posted on May 8, 2019March 12, 2024 by rob.fullsend

Do you need a new boiler?

Boilers help to keep our homes warm and our water hot. But unless these two things stop happening completely, it may be hard for you to detect when you need a new boiler. Having your boiler regularly serviced and having maintenance work carried out can prevent the likelihood of a big breakdown.

But don’t fret, there are a number of telltale signs that you can look out for that indicate that you may need a new boiler installed in your home. A mix of age issues, possible smells and the time it takes to heat up your home can all be signs of issues that may arise. Here at Kiasu Workforce, as a team of boiler experts, we’re here to tell you exactly what you need to keep an eye out for.

Age

Boilers aren’t installed with an expiry date, so there’s no exact way to tell how long they have got left in them. However, a good indicator of how healthy your boiler is is how many years you have had it. On average, it’s best to start thinking about a new boiler once yours reaches 10 years of being installed. It may not necessarily be on it’s ‘last legs’, but new technologies are constantly emerging when it comes to boilers, meaning a newer version is likely to be more efficient.

Smell

You wouldn’t think it, with carbon monoxide itself being odourless, but any sort of smell coming from your boiler could potentially be a warning sign of a leak. The smell is simply a sign that the boiler is not burning properly and this is a situation that needs to be dealt with the moment you realise there is an issue. A great way to not get caught out with a leak is to have a carbon monoxide alarm installed to catch them right at the source and indicate that you need your boiler repairing.

Noises

It’s fairly common for boilers to make noises when they are first heating up, but these should subside to be almost unnoticeable so another sign to be aware of is that of any unfamiliar noises. Any loud bangs, clunking or whirring noises could indicate an issue that means your boiler isn’t functioning properly. There could be an issue with bubbles, broken valves or even the heat pump. We suggest turning off your boiler if you do hear these noises and calling out an engineer.

Time

A less noticeable indication that you need a new boiler is if it is taking its time to do its job. Do you switch the heating on but not feel the benefit for quite some time? The majority of modern or newly installed boilers can reach their maximum temperature fairly quickly, so a slow down in a boiler doing its job means it might be time to shop around for a new boiler.

Money

The increase in your bills is also a clear signal that a new boiler could possibly be on the horizon for your home. Like discussed previously, newer boilers are mostly more efficient and can, in fact, save you money. This also works with the above element of time, in that if you’re boiler is left on for longer due to it taking its time to heat up, it’s essentially costing you more money to run so being aware of your bills is essential in getting the best out of your boiler.

5 signs

These are 5 simple signs to be aware of that may indicate that you need a new boiler installing.
