oil boiler

Hi all Wonder if any boiler experts can help out with my ongoing saga please.. We have a 10yr old Grant Vortex 36e oil combi boiler and over the years, we've had a few instances of it dropping pressure which has usually been down to a leaking rad valve or leaking pipe somewhere. Its been good...

Hi we have an oil heating system running from a Worcester Greenstar and Riello RDB oil pump. Unfortunately it ran out of oil and we’ve since topped it up but the system will not fire up. I’ve taken the casing off the Riello and bled the system where the bleed valve is with an allen key but...

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...

Hoping some of you fine people can offer me some advice! We inherited Grant Combi 90 Mk2 Oil boiler with our house. It’s fairly old, guessing 15 years plus and has been a continuing money pit over the last 4 years. We’ve resigned ourselves to a new boiler soon and are saving as such. But...

Hi There, I need to replace my really old oil boiler to a newer second-hand one and I have found a Firerbird Enviromax Kitchen 12/18kw. Can I install this in a different building from the main house instead of the kitchen or it can only be installed inside the main house? Thanks, Janos

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 all, looking for help please! I have the above boiler (serviced last year Jan21). Sometimes it fires up first time but more often than not I have to press the reset button the reillo burner 5-6 times. On each press ( don’t need to hold it in for 5 secs, just push and release) the boiler makes...

Hi What are the regulations around installing a second hand oil combi boiler, am I right in saying they have to follow manufacturers instructions and building regs? Had people install on and it's positioned where I can't take the rear cover off to reach the condensate. The installation...

Hello I'm at my wits end trying to work out what's happening with my boiler and would love if anyone can give me some advice! We had a Mistral oil boiler installed a couple of years back when we had some renovations done on the house. The boiler wasn't kicking in some mornings and called out...

Looking for some advice.... Can I fit both a wet undefloor heating system and also then fit an electric underfloor heating mat? The idea is not to use both, but have the choice of which source of heating will be most cost effective in the future. It is a new floor consisting of 80mm insulation...

I have a 2013 Grant Vortex oil boiler that is always on. This is despite the remote controller turned off, as well as the heating and hot water switches on the boiler turned off. The following Leds are always on: Power DHW Pump Flow Demand Thoughts?

For a oil condensing combi boiler - there is a lot of easily damaged pipework attached to the outside Garage wall just beneath the flue. The flue itself is in a tamper proof wire box. Can I box in this pipework using pvc cladding to protect the pipework and to prevent corrosion by rainfall...

Hi Folks, Im new homeowner and my oil fired boiler has worked fine... until tonight. Last night was working at "turning down" a radiator upstairs to paint behind it - I didn't fully drain the radiator as Im lazy and saw a video where I could just undo the valves at each side after isolating the...

Hi everyone, Sam here. I have a Worcester Greenstar Heatslave 18/25 Oil combi Boiler. It was fitted in 2009, I bought this house in 2018. For the past 4 months or so, it’s had an on and off lockout issue. Neither the boiler or oil tank has been moved. The plumber I use is happy with the fumes...

Current setup - Heating: Oil fired boiler for central heating, with a separate heating pump. (plugged into 3 pin mains) Hot Water: Electric immersion heater, controlled manually by a regular switch. No timer etc Would like a Google Nest Smart Heating Control – assuming it will control the 3...

Our domestic hot water is coming out really hot, too hot to touch. Overall the timings of the heating and hotwater are controlled by a Tado unit which is working fine. There's a Rhino oil boiler that feeds into ACV Smart cylinder and there's an immersion fitted into the cylinder. The immersion...

I have a Danesmoor 15/19 utility (oil) boiler installed and running in a garage. The garage has a standard garage door and a combined pvc door/window. The garage door is not sealed at the bottom or insulated. It being winter there is often puddles of water just inside the garage by the...

We recently had a new froststat installed on our new oil boiler. For some reason since the froststat was installed, the boiler stays on 24/7. Can anyone confirm the wiring is correct in the attached photo via the link. We have a separate thermometer in the same room, so the froststat should not...

We have a frost thermostat for our new firebird oil boiler which is located in a shed outside. When the temperature gets below 5 degrees the boiler is programmed to switch on. When that happens, will the heating come on? I assumed it would turn on in some eco mode to save energy but to still...

Looking at where to place an external boiler, and some guidance on best practice is needed! Very conventional system - heat-only oil boiler, fully pumped, Y plan, indirect cylinder, F&E tank, 7 rads, all in a 2 bed cottage. It's a spring-supplied system, not on mains, so there is only 0.5 bar...
