The central heating is fine (touch wood).
Problem 1 =====It is a real pain getting hot water to the kitchen. I calculate there's 2.3l of water sitting in the pipes which has to be pushed out before any hot starts to appear. And then 2.3l of hot being wasted in the pipe when turning the tap off. Would you agree with these figures and any suggestions?
Problem 2 =====It is very hard to get the flow right either to the kitchen or to the bath (~9m from the boiler). Too fast a flow and the water is cold (see later) and too slow a flow and the water again is cold. Try to dribble it and the water might be hot but by the time the bath is filled at that rate the bath is still cold. Any suggestions?
Problem 3 =====This is a more recent phenonemon but the shower, which is in the utility room hence near the boiler is generally fine but every now and again runs cold in the middle of a shower. Only occasionally but it causes a scream from SWMBO. Any suggestions?
Problem 4 =====Turning on the cold water tap in the kitchen seems to deprive the boiler of its hot water flow and causes it to run cold. Any suggestions?*
Question 1 ======I am not understanding exactly what the temperature LEDs are telling me. If I understand correctly the hot water is heated via a secondary exchanger so the flame heated hot water is just going round and round. Now are the LED's telling me the temperature of that water or the water temp as it being delivered?
I wonder if I have the hot water thermostat set at optimum. The dial is at "14 mins past". The LED shows 80deg. What happens if I set the thermostat too high?
* These bungalows, built in the 1960's, originally had their boilers in the attic and thus fairly central to the delivery points (kitchen and bathroom). Cold water was via a storage tank (still there for cold in the bathroom). A separate tank was used for hot water and I believe that it may have been heated both by the boiler and an immersion heater. An Italian previous owner gave rise to the current installation.
