6 Zone valves. Is that a record?

[Soggy_weetabix]

I serviced a Potterton Kingfisher MF 100 today.

The house had a 22mm zone valve for hot water, and 5 YES 5 zones for the heating system. All was wired into 3 Randall 4033 programmers.

One room stat upstairs, and 4 downstairs. These were situated as follows:

One in hallway
One in lounge
One in dining room
One in kitchen


I hasten to add this was only a big 5 bedroomed house.

Oh, and Drayton TRV4's on every rad in the property.

Why would someone do that?

Every heating valve is under the floor apparently and all circulates by a Grundfos on speed 1!

Eccentricity, or plain stupidity?

Stupidity gets it first

 

[Soggy_weetabix]

I agree Dave.

Im in the process of trying to find said valves, bypass them and remove most of the room stats.

A wiring adventure for soggy me thinks.

well, post a piccy of the wiring centre. i need a larf. obviosly set your camera to "panoramic"

 

[Doctor Drivel]

I would be inclined to leave the zones alone. He has time and temp control of much of his house, he can isolate parts that are not being used - a great asset. Leave it alone. Don't try and fix something that does not need fixing. In fact removing them will degrade the system.

Many years ago I was involved in the design/installation of a new heating system in an old 7 bedroom farmhouse for an electrical consultant. Each room (15 in all) had it's own zone valve controlled by a room stat. On each openable window there were microswitches that shut the heating to that room down if a window was opened. The control panel was like the Enterprise's flight deck. There were lights to tell if (in each room) the stat was calling for heat, the stat was satisfied, the windows were opened. What with night set-back & frost protection the wiring was amazing.

The boiler plant was duplicated and could also serve the swimming pool complex. There were 4 hot water cylinders also with zone valves.

Took me nearly three months to just pipe it all up. All on time & materials I hasten to add.

(We also had to vacuum out the floor voids if we notched out joists, etc.)

Just a small, simple, commercial control system.

[wilhelm]

i honestly aint got the time.

 

[corgiman]

Well I have never seen more that 4

 

[Dan Robinson]

I've worked on a 4, and had to make it a 5 - pump for hot water and 4 zones (one for each floor).

We changed the boiler and had to fit a second pump - time didn't permit to go off looking for relays and whatnot so I used a Honeywell zone valve to act as a realy.


Works very nicely to! Thank god it was before part P though .

 

[corgiman]

gotta love the regs

 

[Stivino]

I've got a 12" thing with a hole through the middle, is that a record?

 

[gas4you]

Wish I had 12" instead of the bloody great thing I've got
