oil boiler

Hi I am about to order a new oil combi boiler and installation, and I am confused over what size boiler. I got three quotes, two of which quoted in person and said two different sizes. One suggested 18/25 and the other a 26/35. Putting aside the cost difference of the boiler, the engineer...

We've moving into a new house with an oil boiler and I know very little about theses systems. The sellers are elderly and getting details on how the system works is proving tricky. They have it serviced etc and says its all in working order, but I'd like to understand what I'm going to be...

Hi everyone, We have a new Warmflow oil boiler (max 2 years old) in a rental house. It's not working and my tenant got a boiler plumber around, who reports that "it needs replacing as the baffles are corroded and warped beyond repair. He said he can’t turn the burner back on again safely". I...

Hi Is it possible for a DIYer to replace the flexi hose leading to the EV on a grant vort pro boiler? I tried to reenergise the EV but it won't let any air in. The hose does look a bit twisted and knackered. What would I need to turn off and release etc.? Thanks

Hi Sorry for another expansion vessel question but I can find this asked previously Had my boiler service yesterday and the engineer said it is full of water and it needs to be drained. He didn't mention anything about having popped. I pressed the valve and zero water came out. I replaced the...

Hi all We stupidly ran out of oil and have since refilled the tank. We know that it probably needs bled first so have been trying with no success to bleed it and reset. The first problem is we are unsure which is the bleed valve as ours looks different to every other one we've seen (it's a...

Hi. I've got an old Camray 5 Combi Boiler with Riello burner. Boiler has not been on for 6 months. Fired up today and red lockout light appears just before burner ignites. Central heating and hot water appear be working fine. Boiler does not lockout or requires to be reset. Flue appears fine...

My oil boiler is producing black smoke and soot. Didn't really notice it but as its on more it's pretty clear and getting everywhere. The soot has been fine but last night it produced relatively bigger chunks for a period, now they're back to small. I have a service booked for Tuesday, does...

Hi, thanks for reading. I have a Worcester Bosch Heatslave 20/25 fitted with an Inter B11 burner. Yesterday the whole boiler was dead including the control panel. I replaced the control panel fuse which had blown. The Control panel came back to life and the fan started and just ran and ran...

Looking to get a new oil boiler. Old boiler is a Worcester Bosch Danesmoor 15/19. Going to replace more or less like for like, but given a new extension going to go for a slightly higher powered version - 18/25. Question is whether to go for the 'Normal' or 'Utility' version. The only...

Hi all, I am looking to get a Hive thermostat installed but wasn't sure if it was compatible with our oil boiler as I recently found out the Google nest wasn't. Any help and advice would be massively appreciated!

Is it possible to install an external oil boiler in an old out door store cupboard? This model does not have a sealed flue available, but then because the space only has the boiler inside it and is not air tight, is this important? I could even replace the door with a louvred door if that would...

We have the above Oil Boiler. Had a selection of new parts fitted over the last 12 months (see below). Everything has been running fine for about 6 months since last repairs. Over the last couple of weeks, any time the CH is switched on, it fires and heats as it should but once the heating is...

Morning all. Another lockout issue with my elderly (Yr 2000) Worcester Danesmoor 15/19 oil boiler. It runs fine most of the time, but on restart sometimes it just doesn't fire. It doesn't seem to happen mid-run, just when it is restarting. The motor and fan runs, and I hear one click (from...

Good afternoon Ladies and Gents, I have a customer whose boiler locks out periodically after at least one hour. My initial thought was the oil supply and checked that and the filter, replaced nozzle and oil supply hose. Ran fine, obviously I can't wait for it to not work. Pump pressure was...

Hello All. My oil boiler (Worcester Danesmoor 15/19, year 2000) was on all day yesterday with no issues, but today it keeps locking out. It fires up ok, but a few minutes later, it stops burning, and then locks out.... which keeps repeating if you reset it. Things I have checked so far: 1...

Evening All. As part of an extension (self) build, my boiler, which is oil fired, needs moving. Am I able to do this myself? It is a standard worcester danesmoor oil boiler (non condensing, year 2000) The piping is very simple, and not being moved very far, so I could easily do that myself...

Would any of you kind folks help me discover why oil is not reaching my boiler's burner nozzle? Is there a surefire way to check an oil pump is functioning? Following running out of oil, I fired up boiler and it went to lockout. The fan starts, motor starts and the motor is going round as I...

Hello. Our current external Grant Vortex Combi Oil Boiler has a problem with the initial hot water supply throughout the day. In summary: - It takes about 5 minutes of running the hot tap until we get hot water. - This is the same whether the heating is on or not and regardless of time of...
