Radiant electric underfloor heating or heat pump underfloor heating?

Underfloor heating is the most luxurious form of heating as its radiant heat is evenly distributed throughout the room—wall to wall, floor to ceiling—right where you feel it the most.

Hard floor surfaces are warm to the touch and with no air being blown around it is totally silent. What’s more, the system is totally hidden from view and, unlike radiators or surface mounted heat pumps, takes up no wall space. This makes it ideal for large open plan homes or those with lots of glazing.

Installation Radiant floor heating is a type of heating system that uses wires, tubes or pipes installed under a floor to radiate heat off of. floor and into the room. Radiant heat normally use electricity for heating elements, but natural gas or oil is sometimes used. While underfloor heating has many advantages, there are also some problems with the system that potential buyers should know before they buy it.


Radiant floor heating is also expensive in two ways. During the installation costs are high because of the pipes or hoses that need to be threaded through or around the floors throughout the house. These cables or hoses are somewhat expensive and labor intensive to install. Radiant heat may also be expensive to use due to the way the system functions. The heat radiates slowly through the room, which takes a lot of energy in large spaces. This can cause electricity bills to increase rather than decrease.


Radiant floor heating systems are not very efficient. They need heat to extreme temperatures to radiate its heat to the room. The heat in the pipes or lines constantly produce heat, but much of the heat dissipated in the floors, walls and air before it is noticeably warmer in the room. In colder climates, the radiant floor system is always running because of the inefficiencies in the system. Some heating systems are more effective than others, namely, water-based system used with ceramic tiles.


The time between when the heat is initially turned on and when the heat becomes noticeable in the room can be several minutes to an hour. This is because the way that radiant heat is working. Radiant heat is like a fireplace. The heat radiates from the floor and heats the object closest to the first, gradually heating the entire room. The time between when the system is turned on and when the room actually feels warm enough to deter some people from using underfloor heating.

Water underfloor heating systems tend to be best suited to new build and partial renovations (projects like a new extension or a new floor slab). The main reason for this is because water systems require quite a large amount of depth (thickness) – a typical floor build up requires 100mm insulation, 16mm heating pipes and 50mm Anyhdrite screed or 65-70mm Sand and Cement screed, therefore when trying to incorporate this into an existing build can be tricky to do.

Water systems also benefit from the multitude of renewable heat sources to warm the water, such as clitech air Source Heat Pump (ASHP) and ground Source Heat Pump (GSHP), Water underfloor heating makes the best use of these products due to the low water temperature that is flowing around the heating pipe. Radiators for example require 60-80d flow temp compared with underfloor heating that can be as low as 35-40d which matches that of a heat-pump.

The main reason as everyday use of electricity cost so high, while heat pump consume only around 1/4 unit of electricity to effect the same heating capacity. The heat pump water underfloor heating will save you much money!
