Jan 27, 2009 · 46 deg is the new recommended maximum temperature for hot water: .iphe.org.uk/databyte/dom_water_scalding_TMVs.pdf so I reckon you got it pretty spot on at 47 deg Duncan. I believe it is more efficient to run water to the radiators at as low a temperature as possible, while still allowing the room to get warm enough, quickly enough.
The water in a heat pump-powered heating system is not as hot as from a traditional gas-fired boiler, and that reduces the output of the radiator. Typically, the mean water temperature from a heat pump is 50ºC (122ºF). That's a ∆T of 30º and abn output …

What is the correct temp setting for a hot water boiler
Over 30 psi boiler pressure will cause the pressure relief valve to open. Typical operating temperature settings on a boiler call for a Low temperature (boiler cut-in) between 120 and 160 °F. Typical operating temperatures on a hydronic boiler call for a high temperature (boiler cuts off) of 180-200 °F.
Answered 1 year ago · Author has 1.4K answers and 1.9M answer views Our baseboard forced water system was designed with a default oil-fired boiler temperature of 180 F, and the total area of the baseboards around the house, needed to keep up on the coldest days, was calculated with that temperature in mind.
Dec 12, 2006 · Often HW radiation is sized for 180 degree supply/160 degree return with an (obvious) 170 degree average. This will give you a radiator output of 150 BTUH per SF of EDR in a 70 degree room. If you have a surplus, the maximum temperature you need will go down. 200 degrees is plenty high given our recent warmish weather.
Most modern boilers will have a digital dial that allows you to set the output temperature. For combi boilers, the recommended output temperature for the radiators is 75 °C and for the water is between 50 °C and 60 °C. You shouldn't need to adjust these output temperatures as …
Although it's quite rare, especially in water that is regularly changed, like in a cylinder, the risk should not be ignored. It is killed by temperatures above 60 °C, so health organisations like the HSE recommend that hot water should be stored at no less than 60 °C.
