    Cost to re-heat coffee, to making a new cup, efficiency of a microwave cooker?

    I will drink coffee cold, cold coffee in the restaurant in Hong Kong cost more than hot coffee. But wife wants it hot, and will not drink cold coffee. So when she has nodded off and wakes up to a cold cup, I am often charged with rewarming in the microwave. Now it is not rewarmed to boiling...

    Why does a tumble drier tumble when moisture extraction not running with delay start?

    I still have a problem with delayed starts, main one is reading the names on the buttons, as don't do it that often, but the times on washing machine we set end time delay, why not simple start time delay? Some have ½ hour increments, and some 1 hour increments, with all it is start time that...

    Willis Heating System

    I see nothing wrong with any of the statements. The side "boiler" we hoped it did not boil the water, on the Aga stove, was piped the same way as Willis. Today we use a hot coil, and the water in the boiler is not the same as water behind the hot tap, but in 1954 when parents house was built it...

    Heating control question with an oddity

    Glad it seems sorted, these faults are a real pain, as I, for one, do not have the equipment to monitor what is going on. Yes, I know I should have it, it is a requirement of my licence, and I do have a wave meter, but it's a long time ago when I took my RAE.

    Advice on EICR failure C2

    Incorrect, an EICR is issued showing the faults, and once you have some paperwork to show corrected it is simply added to the EICR. Something has to have changed, this may not be the installation, it could be the equipment being used in the installation. Seems an odd fault, the question is if...

    What voltage should I recharge my battery at

    It does seem like that is true. I carefully read the advert, no where does it say lead acid, it says not suitable for stop/start, so likely on AGM or VRLA type, it says leisure so would not be used for stop/start anyway. So assume flooded lead acid. The pictures seem to show a top-up plug, so...

    Adding UFH to Y-plan system

    Not that easy, unless using a non modulating boiler. I saw my son struggle, as he had not considered if any route left open, the return water will cause the boiler to modulate (turn down) on each branch, something needs to limit the water passing so the return is cool, until so many items have...

    24v transformer to fit Hager CU

    Three points, one some CU used half a din rail, and it needs the unit to also connect to a bus bar. The hole in the lid does not match all makes. And the position of the bus bar to the DIN rail is not to a standard. With half DIN rail, a third party transformer is a non-starter, with the bus bar...

    Willis Heating System

    Betamax and VHS there was a third V2000 where you turned the tape over, Philips special. I am also not sure, I do know if not enough room it could cause the whole of the cold tank to heat up, once it started. It seems the cut-out could be combined with the thermostat, or it could be...

    Willis Heating System

    There was a council house in Somerset where the gap was not enough, and when the thermostat stuck and the hot water circulated into a thermal plastic tank which failed and killed a baby. This is why there is a minium gap. I think thermal plastic heater tanks should be banned, but they hope a...

    Willis Heating System

    But we are talking about water over 4°C. V2000 was better than both. However, I see your point, you buy a tank with boss already in place for an immersion heater, why mess around putting one outside it even if it works better, It is not the £43 for the unit, it is the cost of the...

    24v transformer to fit Hager CU

    Be it ISO, ASA, BSW, DIN or any other national or internarial standard, there seems to be some problem in working out what is or is not permitted, I have got some 6 inch 10 mm bolts, the problem is part of the device sticks out a hole in the consumer unit which is not in a standard place, hole...

    Bosch condenser dryer not drying after support wheels fixed

    Some do. This was also my thought, we seem to assume all condenser driers work like our own, but water can be condensed out using room air, water, or refrigeration and putting the number into google it seems it is using the last method. The problem, be it any type of refrigeration unit, AC...

    Electric company wont connect me

    That is also my thoughts, I would get upset if I found my energy supplier was talking to someone else about my property.

    Adding UFH to Y-plan system

    I don't like Nest as it does not connect to the TRV heads. However, the TRV head is in essence a motorised valve once an electronic head is fitted. I have in some ways made a mistake myself, I have a C Plan with two motorised valves and two pumps, and it could have in hindsight have used a...

    Is this 6mm or 10mm cable?

    I will try a 6, 10, 16 mm terminal on wire and see which fits.

    Mark/Space control with central heating thermostats?

    I know pre-modulating boilers better quality thermostats used mark/space ratios to stop it over shooting, The instructions for the thermostat shown, said how it would start switching off and on before the set point slowly decreasing the on time reducing the hysteresis. This messed up a...

    Honeywell T40 wiring

    I agree, it does seem odd to rate it 5 watts, that does seem rather low for the relay contacts, and high for power used. At least for digital (on/off) thermostats, would expect that for analogue (up/down) thermostats.
