Retrofit-Heating & Hot Water

Gas Combi Boilers

A 'combi' boiler is a water heater and a central heating boiler in a single unit. It heats water directly from the mains when needed and doesn't require a hot water cylinder or a cold water tank in the roof.

Gas Condensing Boilers

A gas condensing boiler is a highly efficient way of using gas to heat water for heating and general use. It burns gas but the hot exhaust gases are captured and recycled back into the system through a heat exchanger.

Oil Combi Boilers

An oil combi boiler is a dual-functionality heating system that runs on oil and provides central heating and hot water. If no supply is in place then an oil storage tank can be included.

Oil Condensing Boilers

A oil condensing boiler is a highly efficient way of using gas to heat water for heating and general use. It burns oil but the hot exhaust gases are captured and recycled back into the system through a heat exchanger. If no supply is in place then an oil storage tank can be included.

LPG Combi Boilers

LPG combi boilers are heating systems that use liquid petroleum gas (LPG) to provide both central heating and hot water for a property, without the need for separate hot water storage tanks. They are a popular choice for off-grid homes or areas where a mains gas connection is unavailable.

LPG Condensing Boilers

LPG condensing boilers are heating systems that use liquid petroleum gas (LPG) as fuel, and are designed to be highly efficient by recovering heat from exhaust gases. These boilers are particularly suitable for properties not connected to the natural gas grid, as they require an external storage tank for the LPG fuel.

Biomass Boilers

Biomass boilers that use wood pellets are heating systems that burn compressed wood pellets to generate heat and hot water for a building. These boilers are a form of renewable energy, utilizing a sustainable fuel source and can be connected to existing central heating systems. They are an alternative to gas or oil boilers, particularly for properties off the gas grid.

Air Source Heat Pumps

Air source heat pumps (ASHPs) are a type of heating and cooling system that extracts heat from the outside air and transfers it indoors to heat a building or provide hot water. They work similarly to a refrigerator in reverse, using a refrigerant to absorb heat and then compress it to increase its temperature. Air source heat pumps are considered a low-carbon heating option and can be a more sustainable alternative to traditional gas or oil boilers.

Ground Source Heat Pumps

Ground source heat pumps (GSHPs) are renewable heating and cooling systems that extract heat from the ground or water and transfer it to a building for heating and hot water, or reverse the process for cooling. They use buried pipes containing a heat transfer fluid to absorb thermal energy from the earth and then compress it to a higher temperature for use in a building's heating and hot water systems.

Modern Storage Heaters

Modern storage heaters are a good choice due to their improved efficiency, controllability, and potential for energy savings compared to older models. They offer better heat retention, more precise temperature control, and can be programmed to align with your heating needs and energy consumption patterns.

Log Stoves

Log stoves offer a compelling combination of cost-effectiveness, environmental friendliness, and aesthetic appeal. They can be a more affordable heating solution than electric or gas heaters, especially with rising energy costs, and offer a sustainable, often carbon-neutral, way to heat your home.

New Radiators And Distribution Systems

Installing new radiators and a distribution system is beneficial for energy saving because modern radiators are more efficient, leading to lower heating bills and reduced environmental impact. Upgrading to a new system can improve heat distribution, provide faster warming times, and enhance the aesthetic appeal of your home.

Underfloor_Heating

Underfloor heating is a good option for many homes due to its even heat distribution, increased comfort, and potential energy savings. It eliminates cold spots, frees up wall space, and can improve air quality by reducing dust circulation. Additionally, underfloor heating systems are often more efficient and can be more cost-effective than traditional radiators in the long run, especially when paired with heat pumps.

Hot Water Tank Insulation

An uninsulated hot water tank loses heat faster, requiring the heating system to work harder and use more energy to keep the water hot. Insulating your hot water tank is beneficial because it reduces heat loss, leading to lower energy bills and a smaller carbon footprint. It also helps maintain consistent water temperature and can potentially prolong the lifespan of your heating system.

Even if you have existing insulation adding extra insulation to a hot water tank can be beneficial for several reasons, primarily to reduce heat loss, save energy, and potentially extend the lifespan of the tank. Modern tanks often have built-in insulation, but older tanks may not be up to current standards, and even newer ones can benefit from additional insulation.

New Hot Water Tanks

Installing a new hot water tank can lead to improved energy efficiency, lower energy bills, and reduced risk of unexpected breakdowns. Modern tanks often incorporate better insulation and more efficient heating elements, leading to less energy consumption and cost savings. Additionally, newer tanks tend to be more reliable and require less maintenance compared to older models.

New Heating & Hot Water Controls

You can It's a common and often beneficial to upgrade your central heating controls in a way that can improve efficiency and potentially save you money on energy bills. You can upgrade to more modern thermostats, programmable thermostats, or even smart thermostats that offer remote control and learning capabilities.

It is generally a good idea to install additional thermostatic controls, such as thermostatic radiator valves (TRVs) or smart thermostats, on a warm air heating system. These can offer increased comfort and potentially lower your energy bills by allowing for more precise temperature control in different rooms.

Celect Controls For Storage Heaters

Celect-type controls for storage heaters are advanced systems that use electronic sensors in each room to monitor temperature and communicate with a central control unit, allowing for more efficient and targeted heat distribution. Unlike older models with simple input and output dials, Celect systems automatically adjust the amount of heat stored and released in each room based on individual room temperatures. This can lead to better comfort and potentially lower energy consumption compared to manual controls.

Time and Temperature Zone Control Systems

Time and temperature zone control systems allow for the independent scheduling and temperature regulation of different areas within a building. This means you can set different heating schedules and target temperatures for various zones (like upstairs and downstairs, or living room and bedrooms), rather than heating the entire building to the same temperature at the same time. This approach provides greater comfort, energy efficiency, and cost savings by only heating occupied or needed areas.
