installing an immersion switch

Ramonapixie

hi all.
I have a gas central heating system with no immersion switch. on account of this, everytime i want hot water i need to turn the heating on. can anyone tell me what the approx cost would be to install an immersion switch.
thanks.

It is probably cheaper to heat the water with the gas, and can be much quicker, lots of variables like the age and efficiency of your boiler, size and insulation on your cylinder etc

To heat water electrically you will require an immersion element as well as an electrical supply to it and yes a switch

As per the above post, it is likely that it would be cheaper for you to heat your domestic hot water with gas.

Someone's already done the calculations for you

Yep, using the immersion is by far the most expensive way to go in order to heat water - and that's just the running costs. The immersion, plus getting someone to wire it in for you is going to be a chunk of change in itself. I have an immersion in my oil heated family home that's just been renovated, simply because I reused the existing cylinder with immersion and the wiring was an easy run up from the breaker box, but I honestly don't think it'll be switched on more than a handful of times in my lifetime.
