Take air source heat pumps, for instance. They’re not just a hot topic; they’re setting the standard for modern upgrades. By extracting ambient warmth from the outside air, these heat pumps are like the magicians of efficient heating, operating at up to three or even four times the efficiency of traditional gas boilers. That’s energy savings right in your pocket, all while being a bit kinder to the planet.”

Are gas boilers still an option?

Modern condensing boilers are here to save the day. Unlike their older siblings, which waste a fair bit of energy, these boilers cleverly use exhaust gases to reclaim heat, pushing their efficiency above 90%. Those are numbers anyone can get excited about!

Biomass boilers

Biomass boilers are an alternative to oil and LPG boilers for homes that are off the gas grid and better suited to a more urban environment. They are regarded as carbon neutral and can have big savings by switching from fossil fuels. Modern biomass boilers today are much more automated and can be purchased with smart Wi-Fi controls.

Other boiler types

Electric water heating for those with solar PV panels and battery storage: electric water heaters are another option, simply because of the free electricity generated by the solar panels. These can be set to work alongside the power generation cycle of the solar system.

Going Solar

For the adventurous, there’s the Solar Thermal Integration. This has been an option for many years now; it allows you to gather free solar energy for your hot water system. When combined with heat pumps or condensing boilers, it’s like covering all your bases, ensuring you’re as energy-efficient as it gets.

There are two types of solar thermal systems:

  • Flat Plate Collectors: Harnessing the warm air into a refrigerant to be used as a heat source
  • Evacuated Tube: Direct heat from the sun to the water inside glass tubes

Adding solar thermal panels to your heating system might sound like something out of the future, but it’s happening here and now. This technology allows you to capture those golden rays of sunshine and turn them into usable energy for heating your water.

More ways to save

Pairing this solar tech with something like a heat pump or a modern condensing boiler can optimise both devices’ performance. Picture it as team play, each component contributing its part to achieve a seamless, energy-efficient system.

Solar thermal integration is where it’s at. Sure, the upfront installation costs could seem steep, but think of it as planting seeds for future savings. With energy prices always on the rise, tapping into a free source is a smart move.


Before diving into the world of new modern heating systems, it’s wise to make sure your home is locking in as much heat as possible. Think of insulation as a trusty old sweater for your house; without it, any heat you generate might just wander out into the chilly world beyond.

Keeping the heat in

  • Loft and wall insulation are key players here. Upgrading these areas helps ensure that heat isn’t making a hasty exit right after you’ve generated it. It’s all about sealing those sneaky escape routes. An extra layer in the loft or filling up those cavity walls can make a massive difference in keeping warmth where you want it.
  • Draught-proofing might sound like a simple fix, but plugging up gaps around windows, doors and floorboards keeps cold air from sneaking in. It’s simply plugging the holes for unwanted draughts.
  • Radiator reflector panels: These nifty additions bounce heat back into your rooms instead of letting it seep through to the outside. It’s a small investment with a big payoff when it comes to keeping things warm.

Gone are the days when a single thermostat called the shots for your entire house. Now, smart and zonal controls are here to revolutionise how you manage your home’s heat. With these, you get precision control, room by room, ensuring each area is just right for its specific use.

Control is key

Smart thermostats are the headliners in this scene. They learn your daily routines and adjust temperatures accordingly, even letting you manage everything from a simple app on your phone. It’s like giving your home a brain that’s focused on keeping you comfy without wasting energy.

Thermostatic Radiator Valves (TRVs). These gadgets allow you to set different temperatures in each zone of your house. Want cosy warmth in the living room but a cooler vibe in the bedrooms? Done! These simple add-ons give you that level of control and comfort.

Boiler interlock systems round out your smart setup, ensuring that your heating and hot water systems are in sync. This means the heating system switches off entirely when your target temperatures are reached, saving energy and giving your boiler a much-needed break.

Intelligent, zonal controls: you’re not just automating your heating system; you’re tuning it to your lifestyle. The benefits are clear: a perfectly heated home tailored to your needs and a dip in unnecessary energy consumption.


When modernising your heating, upgrading your radiators and pipework can be a very good move. Modern heat emitters are designed to work with lower flow-temperature systems, along with higher flow rates, which is a must for heat pump systems.

Making them work for you

Radiator upgrades: For example, investing in low-water-content or larger panel radiators means they work more efficiently with systems like heat pumps. They channel water better, delivering heat effectively and swiftly throughout your home. It’s all about optimising performance with your new heat generator.

Underfloor heating (UFH) might just be the game changer you didn’t know you needed. This set-up operates at lower temperatures, making it the ideal companion for renewable heating systems. Besides the radiator-free wall space, radiant floor heat feels like a luxury upgrade in your everyday life.

Magnetic system filter: Don’t forget about the less glamorous but equally vital system filters and pipework. Installing a magnetic system filter catches metal sludge that could muck up your new setup. It’s a minor detail that plays a big role in preserving the efficiency and longevity of your entire heating infrastructure.


When you’re revamping your home heating, don’t skip refining how you generate domestic hot water. We call it DHW for short. It plays a crucial role in your household’s comfort, yet it’s often left in the background. Let’s bring it into the spotlight.

Hot Water Cylinders

Hot Water Cylinders: First off, there’s the choice between vented and unvented cylinders. Vented ones are typically fed by a cold water tank and are a tried-and-trusted method. Unvented, on the other hand, connects directly to your main water line, offering consistent pressure for a more modern twist. This choice often depends on your current system and future needs.

Think about the sources available for hot water production. Do you rely solely on a boiler, or could there be a mix, perhaps with a heat pump or solar thermal panels? Each source has its distinct benefits, and there’s no one-size-fits-all here. Whether you’re leaning towards staying traditional or opting for a new mix, make sure it’s suitable for your household.

Correct sizing is essential. Choosing the right cylinder size ensures you have plenty of hot water without unnecessary energy consumption. It’s a balance of meeting your needs while not overdoing it, saving resources and money in the long run.
