Turn the boiler off. Connect a garden hose to the drain bib. Shut the water supply valve off.
Open the drain bib and drain boiler. Close drain bib and open supply valve.
When boiler is full, go to the farthest faucet and open the hot water and let run.
Go back to supply valve and turn off and on a couple of times rapidly this will "bounce" sediment loose.
Repeat above twice.

I have an Atwood GGA-8E about 6 months old was getting hot water but now the water is only luke warm, any adjustments?


There should be a temperature setting on the gas valve. It should be on top or front and have several settings normally vacation, warm and hot. Rotate dial towards hot setting to increase water temperature. Hope this helps. Thanks

Mira Sport shower running luke warm


Your hot water must come from your coil in boiler and not from a seperate hot water heater - more then likely furnace hasn't been on for heating your house nor has it been on for any draw of hot water. You have to wait till it goes on and brings the water temperature up to your setting or get a hot water tank put in or a new type wall mounted gas instant hot water unit.

RAds don't get hot anymore


rads not heating could be down to old system ie pipework etc and sludge building up. r there any cold spots on rads? when boiler turning off do u mean going to reset? if so could be over heat prob at boiler . there should be a pressure pipe coming from boiler going to outside if its a combi. if this is leaking your expansion vessel might need re charged as this is where the water will be going.

Valient combi boiler is not heating the water properly


vailant boilers are one of the best on the market and should last you more than 6 years depending on installation and servicing.
the engineer you had should not have replaced the diverter valve if the boiler was firing up when the taps are opened. if you was getting luke warm water with the boiler alight it is a classic symptom of a blocked plate heat exchanger on the central heating side.
a new heat exchanger can cost around £100 depending on the age and model of the boiler.alteranatively it could be descaled but may clogg again. it would be a good ideal to fit a magna clean filter on the system to help prevent further debris if you have a dirty system .if you don't trust your engineer i suggest you ask another. find out if he is registered first and don't pay until you are satisfied with the work. if you are asking the same engineer back try and get a discount off the work as he has failed to rectifiy the original fault and fitted the wrong part due to wrong diagnostics. if he is registered you can complain to the governing body ie corgi or gas safe register.
good luck.

Have a combi boiler and the hot water from my taps are running cold to luke warm. My British Gas engineer has told me it is nothing to do with the boiler but is caused by a faulty thermostat cartridge in...


Modern shower valves have an "anti scald device" in them to prevent scalding from to hot water.

They come preset at 120 degrees.

Sometimes they can start to malfunction and all you get is warm, not hot water, they can also be intermittent.

This will only effect the shower valve though, not the other faucets.
