The 3 tube Contra-Flow principle means that there is 30-50% more warm surface area than with twin or single tube systems. The two 'outside' tubes flow in the opposite direction to the centre tube.. Meaning that where the centre tube is coolest (at the return) then the 2 outers are at their warmest, and vice-versa. However after a few minutes operation water temperature is equalised in all three tubes by temperature with no 'cold spots' (a major drawback of the single direction system).

Why aren't more people fitting underfloor heating to new build houses?
Underfloor Heating is perceived as being
considerably more expensive than a
conventional radiator system even though this
isn't the case, in reality there is very little price
difference if any.

Can your system be used with off peak electricity as the main fuel source?
Our system can be used in this way, you would need to use an electric boiler, or one of our own electric thermalstores.

Is the system more efficient with particular floor coverings ie. laminate, wood, sandstane, farmhouse flags?
Sandstone and Farmhouse Flags would be more efficient than wood and laminate, to counteract this we would include more tubing in wood and laminate floors.

I have an underfloor heating system, is it safe to use inhibitor products in the water (Fernox or Sentinel) ?
If it is our system you have you would not need, to use Fernox or Sentinel as all our components are non-ferrous. If it is not our system you would need to check with whoever supplied you with the system.

Roughly how much would it cost to heat a standard 3 bedroomed timber frame house per month using your system?
It is difficult to say exactly how much it would cost for the above.
But for a bungalow of 1,500sq.ft., solid floor construction, with 75mm insulation, timber battens, t & g chipboard floating floor, 60,000 BTU gas fired condensing boiler, supplying hot water to stainless steel Kee Thermalstore, Bungalow divided into 4 zones, each controlled individually by time and temperature. Running cost of heating and gas cooking for house works out roughly at £34.00 per month.

How long does it take for the system to heat a average 3 bed house from cold? i.e if you have just come back from holiday the system is off and its winter?
We recommend a set back temperature. Which would protect your house from frost as well. From say 10 degC to 20 degC. Approx 3 hours. From normal setback 16 degC to 20 degC 1-1.5 hours.

Can the system be connected directly to a combi with integral pump eg Worcester Bosch 400 RSF without using the thermal heat store as this boiler has it's own integral one?
The system can be connected directly to a combi without a thermalstore, you would use the heat exchanger option instead.

Why does the system need to be non-ferrous
Our system is non-ferrous, because we take a very responsible view on oxygen within an underfloor heating system. Oxygen can get into underfloor heating systems through the tubing, so our solution to this is to seperate the underfloor water from the water in the boiler side (by using a thermalstore cylinder or a heat exchanger), we then supply all non-ferrous components on the u/f side so that oxygen poses no problem to our system.

We are building a new bungalow and would like underfloor heating but would also like solid hardwood floors. Most of the solid wood floor suppliers do not recommend underfloor heating. What are your recomendations?
There is no problem using our underfloor system with hadwood floors as long as you follow our directions for wood floors.

Is the heat from the pipes likely to be a problem for floors in an old house? My house is 120 years old with oak boards ground floor & pine upstairs. My 120 year old house has oak floor boards ground floor & pine boards upstairs.
The heat will not cause a problem. In a situation like this you build the heat up gradually within the house.

Can you use a rayburn with the underfloor heating system.
Yes, a rayburn will work very well in conjunction with our system.

Can underfloor heating be used whenever hot water is needed for say 2 power showers?
Yes, you can use the underfloor heating at the same time as 2 power showers, this option works well if you use one of our thermalstore cylinders as you have seperate coils for underfloor heating and hot water.

Do you have an approximate cost per square area for the system
There is no approximate cost per square metre, you find that the more square metres you have, the price per square metre comes down.
