  • Water Heating Calculator for Time, Energy, and Power

    Mar 13, 2016 · I'm looking at a 50,000 btu boiler with a heat exchanger to heat a 33,000 gallon pool to 90 degrees f. I've run then calculation through the formula above, and it's coming up with a 600,000 btu boiler to raise the water temp (68f) in 5 hours to 90f, which seems to be a really high number?Learn More

  • 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 …Learn More

  • Communal Heating and CO2 Air Source Heat Pumps - Heatweb Wiki

    When designing for heat pumps this would normally require topping up boilers, however the CO2 heat pumps can deliver 90C if needed, making it possible to weather compensate the network and keep pipe sizes down. File:Q-TON_en.pdf; The following tables show the COP performance in the 60-65C range.Learn More

  • Daikin Altherma Low Temperature Small Monobloc Heat Pump

    Oct 08, 2021 · If I set the boiler to 65c and the cylinder thermostat to 60c, the hot water from the hot tap reaches approx 40c max. If I leave the boiler at 65c but bump the cylinder to 70c the hot water remains at 40c and the pump runs constantly. If I increase the boiler temp to 75c, then I get hot water at about 50c and the pump turns off.Learn More

  • iPump anyone? How intelligent heat pumps could replace gas

    Jan 23, 2013 · Heat pumps are not a new technology; the principles underlying their operation were described by Lord Kelvin in the 1850s. On the wall of the boiler room of the Pimlico District Heating Scheme you will find a Times article from the 1950s proposing a heat pump as a replacement for the then common open coal fire.. But while they are common on the Continent, their uptake in the UK has been …Learn More

  • Do I Need Low Temperature Heat Pump Radiators? - …

    The maximum temperature that we recommend you set your radiator output to is 80 °C. If you have a conventional boiler system, your water cylinder will have its own thermostat. This is usually fitted on the side of the tank. You should set the temperature between 60 and 65 °C but for maximum efficiency, it should be set to around 60 °C.Learn More

  • heating - Setting radiator temperature to save energy

    I am assuming you have a condensing gas boiler. If you have a hot water tank that is heated by the same system, then you need the boiler set to 70c, so that the hot water tank can get up to 60c, unless you have a very advance system that lets you let the boiler flow temperature to a different value for the radiators and the hot water tank.Learn More

    Oct 18, 2021 · To heat your home quickly, the boiler thermostat can be set high, so the water temperature sent to your radiators is higher. A hotter radiator heats the room more quickly than a cooler radiator. Later in the day, your home may already be warm, and you may only need to raise the temperature by a couple of degrees.Learn More
