Wall heating systems work very similar to underfloor heating in that they heat a room predominantly by radiation (like the sun) as a result of pumping warm water through looped pipes.
Wall heating systems are often used as an alternative to UFH in renovation projects. Until the recent additions of retrofit and wall heating systems, installing ufh resulted in the floor having to be excavated. Although Retrofit UFH kits have eliminated the need to fully excavate flooring, this does not mean wall heating systems are now redundant. It is not always economically viable to re-lay flooring after installing ufh such as in renovations of older homes.

4.1 Ceramic Floor Tiles
Ceramics work well with underfloor heating. They have a nil or very low TOG value and offer very little thermal resistance to heat transfer.
To avoid cracking of the tiles flexible adhesive and grout should be used. Check that the adhesive and grout is suitable for use with underfloor heating.
Underfloor heating is a great addition to any home, lowering your energy bills and providing your home with a more efficient heat source. However, you might be worried about how to install underfloor heating, or if you can install underfloor heating with joisted floors. Well don't worry, here are examples of how you install underfloor heating with solid and joisted floors:
Underfloor heating is a great economical way of heating your home. Whether you are considering adding it to a building, as part of an extension, or as part of a new build or a renovation and it may be domestic or commercial.
1. If you have a fault once the system is up and running, the first thing to check is the flow rate in the flow meters. Make sure they are set between 1.5L/min and 2L/min for boiler use and 1L/min for heat pump use. If there is no reading (the red indicator is at the top) nothing is flowing around the loop.
2. Then take off your actuator heads, if you then get a flow or your system then works you know it is an electrical problem. If after taking all the actuators off you still have problems then it will be a flow fault
We answer your questions about laying underfloor heating onto existing floors.
Dust allergies give many people a stuffy or runny nose and itchy and watery, red eyes. They can also make it difficult to breathe triggering asthma symptoms, such as tightness in the chest, shortness of breath, coughing and wheezing etc.
There are two types of underfloor heating: gas-powered (wet) underfloor heating and electric underfloor heating.
In wet underfloor heating systems, heat is distributed around the house via thin pipes laid under the floor. These pipes carry hot water around the home so that it can release its heat through the floor and therefore warm the rooms where the underfloor heating system is installed. The water is heated in the main boiler of the home.
In cases where the boiler supplying hot water for the household is gas powered (as is the case in most UK households) this type of heating system is known as gas underfloor heating.
An electric underfloor heating system, on the other hand, uses electric wires fitted beneath the floor to provide heat. When an electric current is passed through the wires, they become hot and that heat is transferred through the floor to the room above.
One of the most frequent questions we get asked from customers wishing to retro-fit underfloor heating (UFH) is what is best/most cost effective, excavate the existing floor or add a board system?
Whilst costs can vary hugely by area, tradesman etc., we've compiled a list of comparative costs for each type of UFH install and labour etc. on a typical approx. 75m2 project:
