How to specify and size plans for Hydronic Heating
CONVECTOR RADIATOR PANEL SYSTEMS
We suggest you email or take your house plans to our "enter store" or one of our "Green Homes" preferred installers to establish radiator sizing and a layout design this can then be quoted for 1. supply and install or 2. supply only.
There are some simple rules to go by if you wish to install a hydronic system with your own plumber.
For energy efficient homes you will require approx 600 watts of heat energy per 10m2 of room if the ceiling height is 2.4m, for every 300mm increase in ceiling height add another 100 watts of heat (each radiator has heat output in watts listed in the sizing tables)
For non-energy efficient homes allow 1000 watts or 1Kw per 10m2 for 2.4 ceilings add another 100 watts every time the ceiling height increases by 300mm.
Where possible position radiators under windows and ask your plumber to use insulated piping.
If you want to size the project accurately than rooms that have external walls and windows or glass sliding doors should have allowances made for your heat load calculations.
The type of water heater used is critical and we have a fantastic range of Natural Gas, LPG and highly efficient Heat Pump water heaters, we can help you select the best option for your situation.
If heat pumps are being used (heat pumps operate at a lower temperatures than LPG or Natural Gas) then you will need to increase the radiator size for each room, dont worry this does not increase costs by that much.
Only use heat pumps specifically designed for hydronic heating, as different heat pumps put out different temperatures (most models 45-55 degrees Cel and the CO2 types around 55-65 degrees Cel) . Also note that CO2 Heat Pumps are not affected by low ambient air temperatures like other types of heat pumps and are much much quieter whem running. (you have to put your ear up to the unit to confirm they are on)
Also be aware that some Radiator Manufacturers and Resellers are still quoting the old British Standard kW Output for their radiators according to DIN4704, this basically represents a false elevated output for water heated to 90 degrees Cel. Our Radiators outputs as specified are specified to the current European and internationally recognized standard EN442 so our highest out put is measured on water that is 70-80 degrees which is typical of most gas fired boilers currently on the world market.
Be aware that some companies will under quote heatloads required and take shortcuts when it comes to in wall structural battens for mounting the heating panels.
To be sure your building's heat loads and radiator sizing has been correctly calculated, we have developed a heat load program that will accurately establish your specific heating requirements, thus allowing you to compare quotes on a level playing field, for more info click on this link. More Info
IN SLAB FLOOR COIL SYSTEMSPotential customers will need to provide floor plans to their enter store or one of our "Green Homes" preferred installers so that heat load requirements can be accurately calculated and an efficient energy source can be specified, We then will be able to create an accurate supply and install or supply only quotation. If you are obtaining other quotes do not fall for the "over the phone" estimate these can be miles out and many companies often have hidden cost clauses and may undersize your project to win the quote. The type of floor coil they offer is most important, there is some real rubbish about do not get caught.
