Thread: Central Heating (Hot Water) question

I had a new bolier fitted yesterday and the plumber told me that it makes no difference if I leave the hot water setting on the programming unit to 'On' all the time and there is no point in using the timer. He said that having it set to 'On' will not be using energy, unless we are using hot water, i.e the system stops heating when the water gets to a certain level and temperature and will only kick in (even if 'On') if water is used. If we are out during the day and not using hot water, leaving it 'On' will not be doing anything or using energy.

Is this true and if so, what's the point of having a timer anyway

of course it matters think about it will constantly kick in to keep the water hot like reboiling a kettle over and over - if it's on a timer it kicks in at certain times.

Leaving it in the on state means its a constant level of energy consumption and probably more efficient than stop starting, like aggressive accelerating and braking in a car drinks more fuel than driving at a steady speed.

Why you'd need a timer? Depends on the age, how sophisticated your system is I guess but people will always want to have that control whether it be setting the heating to come on at set times or just keeping the hot water and central heating settings seperate.

Honestly mate I aint got a fucking clue but my answer sounds pretty plausable. That said the guy could be a complete chancer and has fed you a load of flannel.

How was his arse crack?

I think that works with the heating, more economical to keep it on low

My water is always on and I am a tight git so it must be ok. My central heating is hardly ever on except in the winter and is on a timer. I only put it on to keep the kids warm otherwise I would leave it off permanatly and just wear 2 jumpers.

Thanking you

Memph his ass was ace and he had CK undies - yum!!!

Come on now, your just careful are you wearing that nice fluffy pink jump I sent you last Christmas.

I assumed the heat Master generated from wanking meant he has no need for central heating, probably keeps his neighbours either side toastie as well.

We've got instant hot water, biggest ever waste of water if you want hot cause it has to run for a long time until you get the warm. So we fill the kettle when filling the sink for the dishes as we boil water to drink and cool it and filter it anyway.
But they shouldnt sell instant burners in Australia we have big water shortages out here!

Memphis is right I think, its all down to switching on and off,uses more power to draw current through the ass crack.

Bit like you, Hot and liable to kick in shit at certain times.

I have triple AAA washing machine that heats the water and therefore saves the water. Energy light bulbs around the house, combi boiler, insulation in the loft.

I am thinking about getting solar panels and a wind mill.

If you're in the house, the thermostat maintains the temperature and there's no need to shut the unit off. If you shut if off, the water will eventually cool and it will take more energy to heat it back to where you want it. But if you're out for the weekend or on vacation, it makes sense to shut if off, because if not the unit will be maintaining a temperature that is not going to be needed for several days.

I leave mine on all the time... no idea if its cheaper or not as I have always done this because I hate being cold and never let the house drop below 21 during the day and 18 at night all year round but the wife always maintained it is false economy turning it off and on all the time for the heating up from cold reason.

You must be incredibly rich to have it on all year round. I put it on 7am to 8.30am and back on 3.30 to 9pm and that is all for about 6 months of the year and my gas bill is about £800 per year.
