Any apps for calculating flow...

[chris watkins]

When the gas & water bills come in after this idealistic installation has been completed you may find the patten of usage changes!!

As the man of the house of course your wife will be getting up earlier than you from then on & will shower in 2 minutes, get the kids up & washed, leaving you free to rise at your normal time have a nice shower before going downstairs the enjoy the cooked breakfast she has prepared lovingly for you.
or an I being idealistic now ?
You are clearly earning too much now Mutley.

All these heads these days have multiple options for spray patterns so you can choose which suits hey.

Meant more the rose type ones initially re 300-200mm being better flow. That said all the good makes Grohe, Hans Grohe, Kohler and some Aqualisa offer great flow & flexibility for sure.

So, I am getting my A into G with this install now. Just wondering what the best way to install a unvented in the loft as this is going to be a lot of weight. Usually you just stick it over a load bearing wall but not sure if this is the case with a cylinder like this? Do people get structural engineers in for these installs?

Cross beam at least 4 each side of the cylinder even better over two supporting walls

As for size depends on cylinder l

Hi Shaun, thanks for the reply. It will be around 440kgs. Just been doing some calculations and 50 x 100 joists at 400mm centres and a span of 1.8 will do 0.5 KN/m2. I need around 1.7kn/m2.

6x2s ? I would think that would be around the spec

 

[MOSSEP]

Hans Grohe make good shower heads, their shower valves are good as well

Do you think 2x6s would be ok for this then. I can span 2 brick walls of a room below which is a 2.4 metre span in the opposite direction of the joists. The tank would probably be in the centre of this span though.

Cheers. Trying to get a structural engineer but none of them are really that interested.

I would think it would be more than good enough if you span on two supporting walls

You tried phoning building control

No, not called building control. Are they likely to help then?

Yes they should / should give you guidance you know your spam etc

 

[mutley racers]

So I ended up getting an engineer in and this is the outcome.

Only just fit mind you.

Does anyone fit Viessmann at all. I am installing there 100-w system boiler with weather comp and want to know which programmer timer is best suited. Cheers all

@townfanjon

If you can go for the 4 pipe sys

@townfanjon

Not going to go that way. Going to do standard system I think

 

[ShaunCorbs]

You will need the cylinder demand box else the cylinder will only get weather comp temps

 

[mutley racers]

Ah I see. Looks like I need to read the manual before piping up then. Thanks as ever Shaun

 

[mutley racers]

So with my system It is best not to use weather comp with 3rd party cylinder and viessmann controls don't have very good reviews.

Can people tell me what controls they are fitting these days for system boiler. Nest, Honeywell or Tado. Tado would have been my preferred option but I think they have been rather cheeky in putting a 3 monthly subscription to use the geofencing part.

Cheers

 

[ShaunCorbs]

Don’t have any issues with 3rd party cylinders all you do is put a temp sensor in

@townfanjon any help ?

The temp sensor should only be used in V cylinders , ( its a brexit law ) people do though .

 

[ShaunCorbs]

What’s the reason for that I always took it as just a standard temp prob ?

 

[townfanjon]

From what they have told me , its something to do with the patent that V developed when they could do away with a spring return 2 port . Others copied but shouldn’t have , usual crack , nobody's going to find out .
It may have changed its at least 10 years since they told me .

 

[ShaunCorbs]

Might be worth a phone call to Viessmann tech mut

 

[mutley racers]

Thanks guys. I did call Viessmann and they said they don't recommend it.

 

[ShaunCorbs]

Even with the cylinder demand box ? As that controls the safety port valve ?

 

[mutley racers]

Not with smart controls according to tec
