@Razor900 @muggles Why is that? I understand that the pros of the X range are that they look more attractive with the touch panel, have better flow rates and modulate lower but what are the cons and does Intergas plan to address the issues? I hope there aren't reliability issues with the...

To achieve hot water priority, my understanding is you can keep your S-plan heating system and it will only require a little rewiring to achieve hot water priority. This method is called "X-plan", I believe this term was coined by Intergas themselves. The normal approach to HW priority was to...

I have had personal experience of an open vented thermal store in an apartment for 8 years and I am glad I switched to an unvented cylinder. What the sales brochures don't mention about thermal stores, but the installation manuals do, are the various components you need to install with the...

If you are going to use plastic, why use nasty Toys R Us plastic that literally crumbles in your hands like sand? Surely there is a tougher plastic that is more resilient to heat, pressure and chemicals? Different engineers complain that Worcester Bosch plastic flow turbine adaptor...

This is what happens when famous companies like Worcester Bosch think they can live on their past reputation and their "German" name and get away with using plastic or composite components in their boilers instead of brass and unfortunately most consumers won't notice. Watch from 42 seconds...

I was looking at the same boiler too and I came across a boiler installer on youtube who was not happy with some of the plastic and rubber components (9.15) found in the Worcester Bosch 2000 and feels the boiler design has gone backwards, even for a boiler that is not designed to be top of the...

Being 'A' rated doesn't say much about the quality of the steel (steel thickness, pressure it can withstand), whether they use branded not proprietary components, quality of the welding etc. OSO Delta Coil cylinders are only 'A' rated because they have thicker thermal foam insulation and OSO...

I believe Spirotech was planning to launch a successor to the Spirotrap MB3, called the Variofilter (or MB4). Its design appears to compete with the Fernox TF1 Omega in that it also has a metal body and a long internal magnet so magnetite collection would be superior (I would like to see more...

I take that to mean that the 'Xclusive' is the system version of the Xtreme rather than the HRX. I wonder how the Xclusive and HRX differ and I assume that Muggles is right that there is still no launch date of the HRX.

The budget model Ideal Logic has suffered pinhole leaks in their cheaply made aluminium heat exchangers. Another common design fault of the Ideal Logic - cracking sump: Ideal Vogue is supposed to be a premium model (has stainless steel hex) but new version has plastic components: Watch...

Wow, collects way better than my Spirotech Spirotrap MB3 because MB3's magnet is on the outside of the filter brass body. The only criticism I heard on this website about the Fernox Omega TF1 brass filters are the valves that come with it are not full bore. So the flow rate becomes restricted...

I will chip in here and quickly mention the Atag gas boiler as you are still in the research stage. The combi models start with iC. Has weather compensation, smart controls and remote monitoring if you want that. Little known brand in the UK but they have a history selling commercial boilers...

@sxturbo, I was thinking of Viessmann too until I found some videos that demonstrate that there are some issues with the fundamental design of some models (not all I hope). Issues with leaking or splitting rubber hoses and some steel heat exchangers that have aluminium end panels that corrode...

Intriguing, interested to hear what info you manage to get from Daikin. It would be enlightening to see a cross section of their heat exchanger to get an idea of the diameter of the waterways. UK Sales appear to have limited knowledge on this boiler at the moment - I guess because it was...

Plus one for Intergas. Fans of Intergas may become fans of Daikin too but it is too early to say. I've read that Daikin have just launched this April their own gas boiler (D2CND) based on the Intergas but with the benefit of a stainless steel heat exchanger and modulates down further to 2.9kW...

I can't speak for other brands, but Gledhill had a horrendous reputation with their thermal stores, you only have to see what reputable engineers say on this site including Dickie. Thermal stores and open vented systems in general are a very British thing. This UK company got into financial...

If the pressure relief valves that are set to operate is between 90°C to 95°C, then under these controlled conditions, safety relief discharge pipework from unvented hot water storage systems can be drained to plastic sanitary pipework. This has been proposed elsewhere on this website by G3...

We had a pulsacoil 2000, a vented thermal store like yours, and it was the most error prone and over complicated thing we had ever seen. It had a PCB board, flat plate heat exchanger, pump and other bits and pieces that would fail one after the other every couple of years. It was designed to...

I don't believe an outside wall is essential for the discharge pipe as discussed elsewhere on this website. We replaced out pulsacoil 2000 with an unvented stainless steel cylinder. Luckily our plumber located the soil stack (vertical waste pipe behind plasterboard) and connected the discharge...
