1. How does a MAGMA underfloor heating system work?
Hot water from the boiler is mixed with cooler water returning from the floor system. This reduces the temperature of the water entering the floor to that conducive with the system design. This temperature could be anything from 42-53°C.

Where a plate system is required the flow temperature could be as high as 65°C. If the system has been designed to operate on a self-regulating mode the temperature could be as low as 26°C.

2. Does the heat get lost in the ground?
Downward heat loss is minimised by the floor insulation.

3. Does the floor get uncomfortably hot?
No, the floor does not get uncomfortably hot as MAGMA Under-Floor Heating systems are designed to comply with DIN (European) standards. The living area's normal running temperature should not exceed 24°C, however, in specific areas, such as perimeter zones, these temperatures can be run as high as 29°C.

4. Can I use a MAGMA underfloor heating system in any building?
Yes, underfloor heating can be used in any building, as it is part of the floor. It is suitable for both new buildings and total refurbishments of older buildings.

5. What floor finishes can I have with a MAGMA system?
Virtually any finish is possible with underfloor heating. Most of our customers use flooring such as wood, tiles, slate, marble, carpet, etc.

6. Does underfloor heating take a long time to heat?
No. MAGMA's unique method of control ensures that the floor temperature is maintained at a constant state of readiness, from which the system will reach its designed temperature within one hour to ninety minutes. Some energy is maintained in the floor. From this setting, the system should reach its comfort level.

In the event of the heating been switched off for long periods of time i.e. weeks or months, it will take longer for the system to reach its required temperature.

7. How much does a MAGMA underfloor heating system cost?
It depends on the type of building. To install, it is generally more expensive than radiators. If designer radiators are used, or special safety healthcare radiators (LST) have to be used then, underfloor heating is similarly priced if not cheaper.

There are savings of 25% to 30% in running costs and this does not address the significantly lower maintenance costs, making MAGMA Under-Floor heating systems a worthwhile investment.

8. How do I know that the pipe won't leak?
The pipe we use is a best quality polyethylene pipe with a life expectancy in excess of 100 years. It is tough, robust, corrosion-free and resistant to scale build-up. MAGMA piping is manufactured under ISO 9001 quality controls. It has a 6 bar working pressure but is resistant to 45 bar.

All installed systems are pressure tested to 6 bar before concrete is poured or the floor is fixed.

9.Can I have both underfloor heating and radiators?
Yes, you can incorporate both heating systems in your home if you wish. If you are extending or renovating you can combine your existing radiators with your new underfloor heating system. In some cases customers decide to put radiators on the first floor and underfloor heating downstairs.
