Heat Pump Renewable Energy
Looking for a sustainable way to heat your home? Heat pumps powered by renewable energy offer an eco-friendly and efficient solution. At Fastwarm® we’ve responded to growing customer interest by expanding our range. With various models available, we’re confident you’ll find the perfect fit for your property.
A heat pump is an energy-efficient, eco-friendly system that heats your home by extracting renewable energy from the air. It offers a sustainable alternative to traditional heating methods, helping to reduce your carbon footprint while lowering energy bills.
Air source heat pumps perform efficiently year-round, even in cold UK conditions, working in temperatures as low as -15°C.
At Fastwarm® we’ve seen growing demand for heat pumps and have expanded our range to provide options that fit a variety of homes and heating needs. With several models available, you’re sure to find the perfect solution for your property.
Air source heat pumps work by extracting heat from the outside air, even when temperatures fall as low as -15°C. This heat is a renewable resource, which means it is naturally replenished and sustainable. By using this renewable energy, air source heat pumps help reduce fuel costs and lower your home’s carbon emissions.
Inside the system, heat from the air is absorbed into a special fluid at a low temperature. This fluid is then compressed, increasing its temperature significantly. The heat is then transferred to your home’s heating and hot water systems, providing efficient warmth throughout the year.
We can supply underfloor heating systems tailored to work effortlessly with the following leading ASHP Brands:

Heat pumps operate much more efficiently than standard boiler systems by working at lower temperatures. Paired with water underfloor heating, they provide a consistent and energy-efficient way to warm your home. With no need for radiators, they offer lower running costs and a reduced carbon footprint.
They warm your home comfortably and consistently throughout the year, making them a smart choice for sustainable heating.
At Fastwarm®, we design, specify, and supply water underfloor heating systems that integrate effortlessly with air source heat pumps (ASHPs).
Air source heat pumps pair perfectly with water underfloor heating, running efficiently at lower temperatures—typically 35–45°C—to deliver steady, comfortable warmth. Unlike traditional boilers, they provide consistent heat across a large surface area, making them ideal for modern, energy-efficient homes.
This combination allows both systems to perform at their best. Underfloor heating works efficiently at lower temperatures, while the heat pump benefits from the long, steady cycles the system supports. Together, they deliver consistent warmth, lower energy use, and a low-carbon solution—ideal for new builds and renovations. Controlled by a thermostat, the system offers precise temperature control and added energy savings.

Lets TalkIs an Air Source Heat Pump right for you?
Here are a few key questions to consider:
Do you have Space to install your Air Source Heat Pump?
You'll need a place outside your home where a unit can be fitted to a wall or placed on purpose built slabs.
The points below need to be taken into account.
Outdoor Unit Air Source Heat Pump
- The outdoor unit must not be placed on its side or upside down, as the compressor lubrication oil will run into the cooling circuit and seriously damage the unit.
- The location needs to be dry and sunny, but not exposed to direct sunlight or strong winds.
- A suitable location must be selected where the noise of the outdoor unit, when running, does not disturb surrounding neighbours.
- The position must allow pipework and cable to easily be connected to the indoor unit (Cylinder)
Indoor Unit Heat Pump Cylinder
- Ensure the indoor unit is easily accessible with plenty of room to carry out works if needed.
- The indoor unit must be installed upright, a cupboard or plant room is ideal.
- The indoor unit must not be exposed to excessive moisture or exposed to water.
- The unit can be install into a garage or outbuilding, ensure the correct measures are put in place to prevent frost.
Is an air source heat pump suitable for your home?
Due to Air Source Heat Pumps producing lower temperatures, its essential the property is well insulated. For best performance a minimum of 2016 Building regulation standards is recommended. If unsure please call to discuss your project.
What fuel will you be replacing?
The system will pay for itself in less time if it's replacing an electric, oil or coil fuelled heating system. Heat pumps may not be an efficient or cost effective solution if you're currently using mains gas.
What type of heating system will you use?
Air source heat pumps perform better with underfloor heating systems and heat recovery systems due to the low temperature being produced. if intended to use with radiators, ensure they are correctly sized based off these lower temperatures. if incorrectly sized this may result in areas not reaching desired room temperatures. If advice is required please feel free to get in touch.
Is the system intended for a new development?
Combining the installation with other building work can reduce the cost of installing the system.
