Pulsacoil A-Class Boiler

Post  CamillaFox on Thu Oct 12, 2017 1:41 pm

I have recently moved into a flat with this boiler but no Economy 7 meter.
Instead of having the boiler on all the time, we have been switching it on before we need to have a shower etc.
How long does it take to heat up the water?
Thank you!

PC A class is a thermal store

A battery stores electricity A thermal store heat.

The idea is to keep it hot. Ready to use.

E 7 would be the answer 7 hours half price during the night.

Sometimes you can get E 10

Depends on the size of unit how much hot water you get

Your hot water goes like this

Cold from the street
Into the
Plate Heat Exchanger.
Sensor detect when you run a tap etc.
A pump then pumps the dirty store water through half of the PHE hence heating the cold water coming in.
Then out to the hot taps / shower.
Remember you have hot water at mains pressure. So having a shower will go through a lot.

When you heat the unit up it will stop when fully heated. It will not run for ever.
If the unit is getting on in years. Try to keep it hot.

Trouble can start if going hot then cold.

So once the water reaches a certain temperature, it shuts off, so not using anymore electricity?

In your honest opinion would it cost me more to keep the boiler on at all times using standard electricity, or more to turn on only when I need hot water?

At the moment I am turning on approx 30 minutes before use. Our electricity bills are looking to be very cheap using this method.

Thank you!

Hi

Your first line I answered.

Download the user manual
Download the installation manual

All will be revealed.

You are not using the unit in the manner it was intended for.

I have read both of these manuals. I do not find them to be very informative, especially to someone who has no idea. Thanks for your help!

Try talking to your neighbours

See what they are doing ref supply, time clocks etc.

In the installation manual it does give various set up ref supplies etc.

I will try leaving the boiler turned on for a day to compare how much electricity it uses. I have read up on Economy 7, I don't think it would suit our lifestyle, plus we dont have storage heaters. It would probably end up costing us more money. Thanks!

If you want cheap.
Consider a decent electric shower.
That would save you money
But in this day & age energy is expensive.
Most people with an A class on E 7 find they have DHW all the time.
And considering it is heating the unit up at half price and storing that heat in readiness.

If you have not got E7 Why not fit a timer to suit your life style / needs ?

Maybe a timer would be something to consider! However if the electricity cuts out when it reaches temperature, is there any need for a timer? Thanks!
