In-slab heating from PAP Heating Solutions - The do's and don'ts

Especially recommended for people suffering allergies or respiratory complaints such as asthma, caused by moving air or dust particles. The system runs on off-peak electricity. Furniture placement is unrestricted. No building modifications are required for installation in a new home with a slab floor. No moving air or draughts, enabling rooms to be adequately heated at slightly lower temperatures. Quiet, clean and safe. No maintenance. A combination of radiant and convective heat provides excellent comfort with little vertical temperature variation, making slab heating suitable for homes with high ceilings. Even heat distribution throughout a room, no hot or cold spots.

The Dos and Don'ts of In-Slab Heating*

Do:

• Switch the system on at the start of the heating season (usually May to October) and simply leave to run.
• Set and maintain the lowest comfortable thermostat setting and keep the system on this. Every degree the thermostat is turned up adds around 15% to the running cost.
• Install a zoned system (the heating installer works this out for maximum efficiency) and maintain an appropriate temperature for each zone. You'll find that 18°C is ideal for living areas, whilst bedrooms can be set as low as 14°C. There are some rooms in the house where you may not need heating at all, such as the laundry.
• Consider installing ceiling fans if your ceiling height is above 3 metre's.

Don't:

• Switch the system on and off to deliver instant heat. It takes at least one day for the slab to heat up to deliver sufficient heat to a room. Slab heating is designed to provide constant warmth, 24 hours a day.
• Use in non-energy efficient homes. When planning your home, consider the energy saving benefits of double-glazing, lined drapes and effective insulation.
• Have the temperature set too high in rooms which face north and get the glorious winter sun! These rooms can become overheated, so consider setting the thermostat at a lower level than other living areas.
