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.
