Have you tried part opening the cold isolation valve to slow the water velocity? edit : NOT the ballofix 15mm isolation ( if one is fitted ) I mean the one inside the cistern.

Dont flatter yourself lol. I'll 'do it' for the good of the thread / members too and, tbph, I want to know for myself as I may well start promoting these through my business. . To summarise, that's 2 members at 3 pints each so next Friday eve is covered ???? Sweet.

Need to speak to them before I can comment tbh. I've not looked at these close enough to cast an opinion but I'll ring Monday and see what the Bobby Moore is. "Please hold the line.......your call is important to us....." ?

The only differences I can recall is some do the extraction and I've not seen it on others. I'll confess to not ever having asked / checked properly tbh, but apart from that they're much of a muchness afaic. If I had to choose I'd go Geberit, as I'd be looking for long term parts availability. That would be my primary concern. Price wise there's not a big enough difference to argue, considering this'll be buried behind your tiles for the foreseeable.

There's a higher risk of spilling a full kettle over you and causing horrific injuries than a splash of boiling water on the back of your hand from the instant tap imo. Waiting for the kettle to boil does my nut in so I'm a fan.

Maybe I should have watched the video first ?

Could you elaborate a little on that please? Are you saying the water stays warm in the pipes ? The scenario your describing makes having the hot return sound unnecessary.

Yes exactly this and all run in copper piping. That's the 'normal' way to do it, but has the Achilles heel of long waits if the HRC is ever turned off ( so basically you'd need to run the HRC from dawn to bedtime really ) as you then have bigger dead legs caused by the 22mm pipe runs. Agree that it's a balance, as the 22mm pipe runs give the flow rates for 2 showers etc so if your happy to run the HRC accordingly then a good option as it negates complex radial pipe work. I guess it's the toss up between a passive or dynamic solution, but an HRC is really for quite adverse situations or folk who value convenience before absolute efficiency.

PM me and I'll fwd the pdf of the manual they sent. Alternatively you can request it yourself. . The unit needs a waste pipe to drain for the cold water cooling system so factor that in when considering a design.

I rang for some clarification. Here was the ( bloody quick ) reply... Nick,My names Jamie, I'm a heating engineer working for Stovesonline. My colleague Susi has asked me to contact you regarding a Woodfire CX series boiler stoves.They are designed to be installed onto pressurised systems. The boiler is tested to work at a max operating pressure of 3 bar.The boiler stove is also fitted with a quench coil, this is basically an indirect pipe which has cold water passed through when overheating. The cold water which is passed through the quench coil is controlled by a overheat valve. The valve has a probe which is fitted into the boiler stove, if the temperature in the boiler reaches 97degc then the cold water flushes through the boiler stove which in turn cools the stove down.I've attached the installation and operating manual for you. Please let me know if you have any questions.Kind regards, -- Jamie Bennett Heating Systems Manager

You stayed in education longer than me I meant it's not full of energy specific to the production of hot water for dhw. ( or poor words to that effect ). Now shut it, and help me say what it is that I meant to say

Please tell me how this ties in with the sunamp enquiry ?

Technically it's storing heat ENERGY so can be do texted anywhere you like. I'll check out the vid later and see what I can derive from it

I'm sure you won't be waiting too long

I can vouch for him What @PeterW said.

07:30 onwards, you're back in business. Sleep now, for tomorrow I fear more ranting. My 6-shooter is loaded, and ready to pick off any trouble makers If we all keep to the facts I may save on ammo. "Have a nice day, Y'all"

Does the hot run in 22mm for the majority and then reduce to 15mm with a 15mm return?

Just glad to be providing a service.

Ok. Boiling tap with blended instant hot water for the kitchen sink, with one assuming you'll have a dishwasher?. Write the expense of the tap off against the cost of the HRC and associated pipework / complexity and running costs. Go for radial plumbing throughout and consider a cold mains accumulator to reinforce the flow rates if your incoming supply is less than perfect. The delay to ensuite 1 will only be apparent when you run the basin hot taps after a jimmy riddle / other. That can be reduced by running them in 10mm. The baths and showers will be relatively high flow rate outlets so by the time you've turned the tap on fully and selected your favourite loofa the water will be hot. The thing to observe is reducing the amount of large bore primary pipework prior to the manifolds for the hot feeds. FYI, I previously plumbed a similar sized property and ran a HRC for just the basins. That worked well as there were a few satellite basins ( WC's ) which would have suffered otherwise. I chose to run a well insulated HRC and also decided to continue a spur off the HRC down to the very far away kitchen sink ( pretty similar to your layout tbh ). I ran the HRC at 50oC to keep the temp,high enough for 'dish wash' and then put individual TMV's ( thermostatic blending valves ) at each wash hand basin to reduce the water temp to make it comfortable for hand washing, negating the faffing about between hot and cold.

Let me dart the last 2 kids then I'll come back to this

Nope. I think this thread NEEDS a night off.

2 day ban for you

I don't think your two concerns are directly related tbh. Having good flow will have nowt to do with a hot return circuit ( HRC ) or standard plumbing, either will be dependant upon pipe sizing, incoming cold mains pressure and flow rates, and your chosen dhw production unit having a good flow rate through it. Which room is the kitchen under.? Can you post the other floor plan please

Tres bien, Rodney.

I really didn't want to embrace this tbh, but seeing the 'shed-in-progress' I have to chomp some humble pie. It actually looks quite good.
