We have had a new system boiler (Glowworm R18) fitted in the property we rent out. The central heating temp is showing 75 degrees on the readout. The central heating system is probably about 20 or 30 years old. Does such a high temp put added pressure on the pipes, valves and joints ?
Would backing the temp down to 60 or 65 degrees reduce the pressure in a useful way ?
