I'm hoping someone can help me work out my central heating system please... I've just moved into a new house with an unvented OSO cylinder, a Danfoss FP720 programmer and underfloor heating controlled by Aube TH 232 thermostats and it is starting to drive me crazy!!
We have 3 bathrooms with showers, 1 of which is on the 1st floor, and the kitchen located in between - The boiler, OSO Cylinder and Danfoss Programmer are all located in the garage. What looks to me as the logical and most direct layout as per sitings or rooms is as follows:
1. Garage and cylinder
2. Bathroom 1 (ground floor)
3. Kitchen
4. Bathroom 2 (main house bathroom, ground floor)
5. Bathroom 3 (upstairs)
I have a few questions about this set up and really hope someone can help me please.
We moved in 3 weeks ago and the Hot water has mostly been ok, there are 4 of us living here (wife and 2 daughters) none of whom ever has less than a 10 minute shower. The water has always taken longer to reach bathrooms 2 & 3 and I presumed this is purely down to the distance it needs to travel through the pipes, possibly 30-40 meters.
Problem 1
The last day and a half we have not had any hot water. The timer and programmer shows the light saying that it is on for both heating and DHW but I can run the tap for ages in all rooms and still don't get any Hot water.
It could be that I am misunderstanding how to use the cylinder and controls properly as I have always had a combi system previously. Attached are photos showing the cylinder and controls on the wall and I believe the programmer is set up correctly and how we want it.
One thing to note - The switch that is labelled "water heater" has not always been on. I have just turned this on today as I thought it controlled one of the immersion elements and therefore essentially kept the heater on continuously - which goes against the point of having a timer and programmer... Is that correct? I started to think that the switch was the over riding...
