Use our flow charts to methodically work through and rule out potential causes of problems with your central heating and hot water supply.
Central heating water tank temperature.
A pumps job is to push hot water around your heating system.
Some boilers have separate controls for the temperature of the radiators and hot water.
Without the pump the water will just sit still in the pipes.
This is usually fitted on the side of the tank.
If you lower the temperature your boiler will operate as efficiently as possible.
1 the boiler has two separate functions.
The water tank has two jobs.
Providing a place for the hot water to go when your system has overheated.
There are many different types of central heating systems on the market most of which comprise a central boiler which is actually a heat generator because the water is not boiled.
You should set the temperature between 60 and 65 c but for maximum efficiency it should be set to around 60 c.
If you have a conventional boiler system your water cylinder will have its own thermostat.
Hot water cylinder capacity varies between 25 gallons to 50 gallons for normal domestic supply with the larger being enough to supply an average family for a day.
This allows you to set the temperature of the water that leaves the boiler to heat the house.
To heat your hot water tank and to heat your house.
3 your programmer contains a clock and two time switches channels which turn the hot water and central heating services on and off at pre selected times of day or night.
Feeding water to the central heating system when water is low.
The location of a pump is usually placed inside.
Central heating faults and fault finding hot water or heating is too hot.
Temperature controls for your heating and hot water.
Its job is to top up your central heating system with water and if your system overheats it provides somewhere for the hot water to go.
With that in mind if you have a hot water tank then your hot water flow should be at least 60c and your hot water tank should be set to store water at this temperature.
Although a small tank may be found in the loft for venting and feeding your central heating no cold water storage tank is necessary.
Rather it peaks at 82 90 c or furnace to heat water pipes to distribute the heated water and heat exchangers or radiators to conduct this heat to the air.
This is because this is.
