Boilers. To condense or not ? | Singletrack Magazine Forum
Be careful with lowering water temps, the radiator is sized to give a certain output (e.g. 1.5kW) at a certain mean water temp (e.g. if your boiler produces 80C water, and the water leaves the

Low Temperature Heating - Energy Stats UK
As mentioned above, heat pumps work best at lower temperatures. So you'd likely need around 40 to 45 degree water in your rads to ensure a high COP (coefficient of performance) with a heat pump. Heat pumps aren't anywhere near as efficient when trying to replicate combi boilers with 50 and 60+ degree heat.

Radiator Sizing with heat pumps???
Jan 27, 2011 · "In My Opinion" firstly I believe that common water radiators are not primarily devices that radiate heat, that are natural convention heating devices, more energy is transmitted to the heated space via convection than radiation! If we look a standard radiator, with use with a boiler, the water is circulated lets say 60C (I know in many cases it is higher), the air temp is …

Help! Different temp outputs for UFH and rads
May 06, 2010 · So a boiler running at 40C/30C will give the same output as one running at 80C/70C. Though, having said that, condensing boilers are more efficient when the return temperature is below 55C, so the output will actually be slightly higher in the first case. Although boiler outputs are the same, radiator outputs are related to the flow, return and

Managing your central heating - Transition Cambridge
Balancing the system is a matter of optimising the radiator valves and the boiler pump rate to get an optimum temperature drop through the whole circuit and in each radiator. If you don't balance the system then the upstairs radiators tend to get all the heat and the last radiators in the circuit take a long time to warm up.

From Gas Boiler to Air Source Heat Pump
Jan 31, 2021 · The cost of a heat pump system will depend on a number of things, principally the size of pump needed; the number of radiators which need to be upgraded; and whether you need to replace your hot water tank. Our 9kw pump, five radiators plus new tank cost £11,400 including VAT, which is a lot of money, but there are things to offset this.
Get A QuoteDo I Need Low Temperature Heat Pump Radiators? - Evergreen
Compared to conventional boilers and emitter systems that operate at around 70-80°C, heat pumps have a flow temperature (the temperature water flows around your emitter system) of around 35-50°C. This has led to a somewhat misleading term of heat pump radiators being called 'oversized', when in actual fact they're accurately sized as
