Can I install a SunFlow® System in any floor type?

What heat source should I use?
In New Zealand, gas and diesel (heating oil) boilers cost more for initial installation, but less to operate. Electric boilers have a lower installation price, but higher running costs. Boilers employing LPG have running costs comparable to electric units. Solar, wetbacks and geothermal power can provide useful alternatives or backups if available.
Can I use any type of floor covering with a SunFlow® System?
Yes! Advise your local distributor of your choice and your system will be designed accordingly. As they are the most conductive, tile, slate and stone floors are the most efficient. Hardwood is next, followed by carpet and underlay; even vinyl and linoleum can be used. Usually the only design variations are tube spacing and supply water temperature.
Is SunFlow® a healthy system?
Yes! SunFlow® Systems do not use air as the vehicle to move the heating through the house. Consequently, mould, mites and dust are not being distributed. Allergy sufferers and asthmatics really notice the difference with a SunFlow® heating system. Another great health benefit is the elimination of damp, mould and condensation.
Is it true that some older systems made the floor too hot?
Yes, to some degree. Older in-floor systems using electric cables ran at high temperatures and had very simple controls. Many floors heated by electric cables consequently developed floor surface temperatures too hot to be comfortable. With a SunFlow® water-fed system, the sophisticated controls ensure the floor temperature seldom exceeds 24ºC.
