Piping hot water in the morning, but none in the evening

Post  heshan on Sat Jan 30, 2010 4:27 pm

Hi Mike

Firstly thanks for running this site. I never knew that this is how my pulsacoil 2000 ran.

I have my parents over at the moment and hence the demand for hot water has gone up. 4 people are able to comfortably shower in the morning with plenty of hot water, but when it comes to the evening, theres very little lukewarm to freezing cold water. The boost function doesnt seem to respond as even after 3 hours of manual boost the boiler doesnt make its characteristic boiling sounds, the boiler doesnt go warm as is usual and ultimately, there is no improvement in water temperature. This issue has been going on for about a week. I filled up my grey plastic tank to about 3/4 full, and have been milling around the boiler waiting for it to burst into life (it was on off peak heating when I put in the water), and its been about 2 hours now and still no noise from the boiler and no hot water.

I havent filled the water tank since I bought the flat about 5 years ago, but when I finally did fill it the water in the tank was far from empty.

I hope Ive covered all the relevant issues to help you diagnose the issue.

thanks

What size unit have you.
Prob to small for 4 people.
If all ok in the morning.
And will not work on boost sounds as if the top heater and or stat may need replacing.
And good electrician should sort it.
Have you checked on this site for any one in your area?
If not Gledhill may help you or recommend some one.

Booster not working?

Hi, you wrote the booster has no impact after three hours? Consider having the booster supply, thermostat and element checked. Most likely the system is undersized but on odd occasions like this the booster should help in the evening.
