I have a clients oil Grant boiler I fitted last year. It is a Vortex pro 26-46 system. It is just a small system loop as it is a pool boiler. Heated through a heat exchanger directly behind the boiler. I went to service today and took about a handful of rust off the baffles. There was even signs...

Hi Oil experts. I had a grant wall boiler with a failed transformer. Carried out a service and pretty sooty nozzle, and baffles build up suggest not cleaned in a while. The bottom baffle on the left corner had completely burnet through. Any Idea on the process on how this occurs and why just...

My Grant combi oil boiler is giving me quite a headache at the moment. When I returned home last Friday I'd no heating or hot water. An engineer called the next day and diagnosed a faulty pressure switch. This was changed and everything seemed ok. However then the boiler began to lose pressure...

Grant Vortex 50/90 condensing oil boiler where the air tube spigot over the fan is not connected to the existing flue, should this be closed off with a Reillo cover plate to stop vermin getting into the open fan motor.If is blanked over will need a further combustion test to confirm adequate...

Following on from my question about monitoring F & R temperatures, I needed a measuring device because the overheat stat. frequently trips and then needs to be reset. It normally happens when the boiler has switched off and is no doubt due to the hot water rising to the top of the boiler, but I...

What is it? It apparently is obvious when one knows it. The last numbers of the serial number for example. Anyway, it hasn't been changed from the Grant factory set password,,, though it is numbers.

Any advice welcome as plumber stumped Had 36-46 grant vortex utility boiler 7 years no problem recently oil tank move and tigerloop install (tank about 1m lower). 10 days later and boiler either doesn't fire or fires stops, fires runs splutters stops. Most it runs now is 10 mins, but that's...

The boiler has a servo motor on the brazier. Does this mean that the brazier opens to drop ash into the ash can? The boiler doesn’t perform the cleaning sequence. I think the program has been corrupted. What is the password to get into the program to check or reprogram?

I have a Grant Vortex Blue 26kw external oil boiler, installed less than 12 months ago. It's had intermittent non-starting problems resulting in multiple warranty visits, part replacements and eventually burner replacement. The replaced burner I discovered was a 'yellow flame' one, apparently...

My oil boiler is 2009 vintage. Just been serviced. Had a new tank fitted by approved fitter. I notice that the bottom of the tank is roughly on the level of the boiler feed pipe. Then I notice in the Grant instal manual for a single pipe feed the tank should be 300mm min above the boiler feed...

Hi, I have an issue with my Grant Vortex internal combi boiler. Specifically the electrical side. Everything was working fine (with a dual channel Hive system) but then the central hearing stopped working. When looking it seemed like there were a number of loose contacts as when we moved the...

Evening everyone, We've been having some issues with hot water coming from our Grant Vortex 21 boiler (external, oil fired, no cylinder) Water has been getting progressively colder over the past couple of months to the point where the little one struggles to have a bath. The hot water pressure...

Hi, I've recently put some heating/hot water pipes into the floor as there were exposed previously. On refit of the pipes i've gone to test the boiler functionality however, the central heating won't fire. The hot water works perfectly. There is no CH light on the boiler and the return...

Hi Installed UFH Manifold, pump, Valve etc, connected to a Saswell scu209led-tm1 Connection Box. On the terminals marked "com" and "no" going to the Boiler. Which terminals on a Grant Vortex Boiler do these 2 connectors go too? Thanks in advance

Recently needing to reset the little red button under the black cap on the boiler about 3 times a week. Always serviced annually. How can I stop this?

Hi all, I have recently run out of oil - the sensor in my kitchen is faulty so we’re completely empty. I’ve topped up my tank today to tide me over until delivery but my boiler (grant vortex eco wall hung) is still in lockout. I’ve read around and think I need to bleed the air from the system...

Hi i hope someone can help, a couple weeks ago boiler was not staying on so i thought i would check rads and i bled them and it fired up and was working for a couple of weeks. Now it fires up and cuts out after about 5 mins. I changed the 2 port valve as pretty much every year this fails. Still...

Hi, We have just had a grant oil combi boiler installed and we have two options to heat our hot water; we can have the water on continuously which will keep the very small water reserve in the boiler at a certain temperature. Or we can have the hot water off and then just boost it when we...

I have a new Grant Vortex 15/26 oil boiler installed. It has a boiler thermostat with no numerical information, just a wedge graphic and covers about 1/3 of a turn. I wondered if anyone could give an indication of what the range of temperatures is likely to be (I don't want to set the boiler...

Hi guys, looking for some advise on my Grant Vortex 26. Had a big leak for the heat exchanger last year which ran down to the hot water pump and shorted it out. I replaced the pump with new and new olive on the offending pipe. But since then have a couple of issues. 1) The hot water tank sounds...
