Underfloor heating systems are the invisible alternative to the standard radiators. They are fitted underneath a house's flooring system and contribute towards a more expansive and simple bathroom design. Once the underfloor structure is put in place, it requires little to no maintenance and it offers a great selection where space is at a premium. it is also a great option for sustainable living. It is important to note that the cost of installing an underfloor bathroom heating system can be significantly high but the system has a considerably low operating costs. Underfloor heating systems do not run as high as the standard heating systems and as an added advantage, they evenly distribute heat throughout a room. This allows you to stay cosy at home and save money throughout the year.

Type of System

The first decision you have to make is what kind of system you would like. You can decide to install a hydronic heating system which employs the use of pipes under the floors and runs hot water  through them. This consequently heats the floors and your room in general. An electric system uses electric coils placed under the floor and it is the best choice for retrofitting underfloor heating systems because it is much easier to fit since it does not need any aggressive pipework.

Cost & Planning

The second decision is the cost. Usually, people let their budget determine their decision and while this is a good move, the budget should also include the running costs. Electric systems are considerably lower priced than hydronic heating systems but their operational costs are quite high in comparison. Hydronic systems may be a little more expensive to install but the running costs are considerably low. Hydronic heating systems will also generally improve the value of your property so this is worth considering when making your decision.

The next thing you need to do is consult with a bathroom underfloor heating supplier such as the one found here, this is important because even electric bathroom heating can be difficult to install depending on any permanent fixtures, sinks, showers and baths in the area. It is also important to note that you should have a gap of roughly six inches between your underfloor heating and any walls or plumbing fittings. To this effect, always order a little more underfloor heating than you need as the extras may come in handy in the event you need to cover any obstinate spaces in your bathroom.


The next step is to thoroughly prepare the floor. An important thing to take note of is that as to realise the full benefits of underfloor heating, the floor must be accurately protected to prevent any pointless depletion of energy. Choosing a floor that has good thermal conductivity such as tile and stone to cover your underfloor heating goes a long way in your heat output. This is because the thickness of the floor affects the amount of time it takes to warm a room and floor alike.

After all these, the next thing you need to do is hire a professional. When installing an underfloor heating system, it is widely discouraged to take on the project yourself as it is a highly complicated process. It is not a candid process as compared to a radiator replacement. So, always make sure you get a professional to install your bathroom underfloor heating system.
