What's underfloor heating and how does it work?
Underfloor heating works by distributing a lower temperature of warm water through a circuit of pipes beneath the finished floor. Heat is monitored and controlled by intelligent thermostats to maintain a consistent temperature throughout the property or individual zones.
How long does underfloor heating take to warm up?
Water-based underfloor heating systems can take up to 3 hours to reach operating temperatures from the point of being switched on. You can expect to feel a warm floor underfoot quite quickly but it will take an additional few hours to heat up the ambient temperature of your home. It takes a lot less time to heat up a water-based underfloor ...
How much does underfloor heating cost to run?
With this in mind you can expect hydronic heating to cost, from: $68 per square metre for an in-slab underfloor heating system (excluding boiler) $105 per square metre for an in-screed underfloor heating system (excluding boiler)
Is it best to leave underfloor heating on all the time?
It is advised that in the depths of winter, an underfloor heating system should be kept on at all times. Although it should be at different temperatures depending on usage and activity in the house. This is because underfloor heating can take two to three hours to warm up, so it is best to not completely turn it off.
What is the most efficient way to run underfloor heating?
The most efficient ways to use underfloor heatingSelect a programmable thermostat. Select a programmable thermostat not only for efficiency purposes, but to avoid the headache of returning to a completely cold house from top to bottom. ... Gradually increase the heat output. ... Annually service your Underfloor Heating.
Should the floor feel warm with underfloor heating?
As a general rule of thumb, your heated floor shouldn't feel hot - it should just not feel cold.
Why is my underfloor heating so expensive to run?
Room Insulation & W/m² Used It's not just floor insulation you need to consider when fitting an underfloor heating system. Inadequate room insulation is a primary cause of higher running costs, because draughty rooms lose heat much quicker than rooms with insulation up to modern standards.
Is underfloor heating more expensive to run than radiators?
Underfloor heating is more eco friendly than using radiators and uses less energy, meaning they cost much less in the long run! As long as you have installed it properly, you could save about 25% of the energy you would use with a radiator, and up to 40% when running from a heat pump.
Should you turn off underfloor heating in the summer?
Underfloor heating can be switched off during Summer when the outside temperature is warm enough. This is because it takes longer to warm up and cool down than other heating methods, making it harder to adjust your settings when the outside temperature is warming your home.
When should I turn on my floor heat?
Unless you're heating a bedroom, you probably don't need your floor-heating system on at night. Therefore, you can turn your system off at night to save energy, but you'll have to remember to turn it on first thing in the morning.
What is better electric or water underfloor heating?
Warm Water Underfloor Heating More powerful in heat output than electric systems plus much more energy efficient than radiator systems and can completely remove the need for traditional radiators in your home.
How much power does an underfloor heating system use?
If your floor is well insulated and you have a reasonably modern home, the power of an underfloor heating system usually needs to be between 14-20W/m² to give the required output. When it comes to choosing underfloor heating, a 15-20W/ft² system is usually specified to reduce heat up times as the system will not be “on” continuously. When the system is only “on” half of the time the room is used, the power provided is half of the Wattage of the system. That is, a 20W/ft² system usually provides 8-12W/ft² per hour.
How to reduce heat loss in a heated floor?
If you don’t want to change the floor finish or can’t change the size of the heated floor area, increasing overall insulation is a good way to reduce heat loss and achieve a lower heat output requirement. Adding cavity wall, roof and additional floor insulation are all good ways to keep the heat in and will lower the heat output requirement of any heating system.
How can insulation increase heat output?
The heat output to the floor surface can be significantly increased by using insulation, such as Warmup insulation boards, under the heating. This may be immediately below the heating units, pipes or below the screed or medium that the heating is embedded within. If no insulation is used, the heat generated will move not only upwards but downwards as well and in the worst case, even heat the ground below the structure wasting energy, money and the heat you require.
How does floor heating affect the output?
The size of the heated floor area is directly linked to the heat output as the larger the heated area, the higher the maximum heat output of the system. However, the size of the heated floor area in relation to the overall room size affects the output too as the larger the room gets, the higher the heat loss becomes. If the heated area is significantly smaller than the overall floor or room size (<80%), it may be difficult for an underfloor heating system to create enough heat for primary heating unless the home is well-insulated.
Why is room temperature important?
An accurate room temperature control is essential in ensuring the correct heat output. A smart thermostat does not only offer accurate control, but can also save money on heating bills.
Can underfloor heating be fitted under permanent fixtures?
In certain rooms, such as bathrooms, large parts of the room are covered by permanent fixtures such as baths, toilet or sink. As underfloor heating should not be fitted under permanent fixtures, in these circumstances only small parts of the floor surface can be heated. This can significantly affect the heat output.
Do you block heat from underfloor heating?
As a final note, bear in mind that once you’ve gone through all the effort of ensuring your underfloor heating system provides enough heat, it is crucial that you do not block the heat being emitted from the floor. Insulating and heat-blocking materials, such as rugs, furniture (especially bean-bag chairs!), will significantly hinder the performance of the system.
How much does it save to turn down the temperature of an underfloor heating room?
Turning your underfloor heating room thermostats down by just 1 degree could save around £80 and 330kg CO2 per year, according to the Energy Savings Trust.
How long does it take for an underfloor heating system to heat up?
With these two figures, you can now work out an accurate timing schedule for the underfloor heating heating system. If you know it takes 30 minutes to reach 21°C, you can set the heating to come on half an hour before you arrive home from work or get out of bed.
Does it matter where heated floor thermostats are located?
Yes, definitely. Underfloor heating room thermostats should be placed in a location where they can receive a free flow of air from the room , to read an accurate temperature for balancing underfloor heating.
Do I need to update or replace my existing heating controls?
A heating system should have a boiler thermostat, programmer/timer, and room thermostats (or thermostatic radiator valves with radiators). Providing you have these, it’s generally just a case of understanding how to effectively use them.
How many types of underfloor heating are there?
There are two main types of warm water underfloor heating and they are controlled in very different ways:
Why delay underfloor heating?
Delay the start-up of underfloor heating to the latest possible moment, to avoid unnecessary heating and ensure the property is warm at the programmed time.
Why use a thermostat for heated floors?
Programmable heated floor thermostats help improve energy efficiency and responsiveness as rooms are controlled at the precise temperature required throughout the day. They’re particularly suitable where different areas of the house need to be programmed to heat at different times of the day, such as heating bedrooms for shorter periods and living rooms from late afternoon into the evening.
