system
A system is a group of interacting or interrelated elements that act according to a set of rules to form a unified whole. A system, surrounded and influenced by its environment, is described by its boundaries, structure and purpose and expressed in its functioning. Systems are the subjects of study of systems theory and other systems sciences.
HI folks, this post is a follow up to my post relating to my single pipe heating system. In summary, I have a house built in 1980 (I bought it 2 years ago) that had a single pipe heating system but over the years there have been some changes made to the system that meant it didn't work. I have...
I am starting a large victorian renovation and it will involve, (amongst everything else) installation of an entirely new heating and plumbing system.
Plumbing, like most trades, seems to have two main aspects; design and installation.
The installation part on my last two projects was painful...
The system is about 20 years old and has never been cleaned. The radiator water looks like tar and several radiators are warm at top and cold at the bottom.
What would be the best steps to clean the system?
I have spoken to several engineers. One only recommends a magnacleanse due to being a...
Hi all,
Got a nightmare situation with a central heating system I recently adopted. It's an open vent system with a combined F&E pipe, with a Worcester greenstar danesmoor 18/25 oil boiler. Covers 10 radiators mostly large double panels, some towel rails and smaller rads too, as well as an...
Hi All
I have a single pipe central heating system which was extended 20 years ago when we had an extension. The heating upstairs has never been great particularly in the extended part with only a few of the original radiators getting very hot. We replaced the downstairs radiators with UFH...
My first post here, looking for some advice.
I've just had my boiler replaced with a worcester 4000 combi boiler. The engineer put chemical flush and inhibitor in when filling up, ran the raditors hot and then tested using a strip. And has left both in saying this is safe, and standard...
Hi guys,
I have a set up with rads upstairs and UFH downstairs. I have installed the manifold for the UFH along with 2x Honeywell 2port values, one near the manifold and the other on the radiator side. I will be using Nest 3rd gen thermostats to control both the upstairs radiators and...
Hi. A new house regulation for a 2 zone heating system because it's bigger that 150sqm.
I'm I right in saying zone 1 should be all of the downstairs radiators and zone 2 all of the upstairs radiators ?
I have thermostat room programmer down the stairs and another one upstairs.
I think the two...
I have a Greenstar 4000 30KW combi boiler, and am planning to partially drain down the system to move a radiator. There is a blue lever ("keyless filling link") underneath for gradually topping up the pressure after bleeding a radiator, but I suspect this would be a very slow way to refill the...
I am currently in the middle of a complete rennovation of my house and need some advice on what kind of boiler to get.
The house will have 4 bathrooms in total. One on the ground floor (shower), two on the 1st floor (en suite has a shower and family bathroom has a bathtub and seperate shower)...
Any ideas why a sealed system with a combi could be grabbing air. The upstairs rads have air in and the system reads 3 bar cold. When the air is bleed out the system returns to 1 bar or less. It's an ideal instinct boiler basically a logic.
Hi,
I have a gravity based hot water system, and recently had a new kitchen installed. We never had a noticeable hot water pressure issue before, but the flow from the new tap is down to a trickle.
Pressure head is c.3m. Flow is 2L/min compared to 12L/min minute out of the hot water tap...

Hi,
We are having PV panels fitted which will dump the excess energy into our hot water tank. Our house originally had a large 210L economy7 hot water tank (cold tank in loft), but the hot water tank died 18 years ago. At that time we fitted a smaller 117litre tank and went for fitting electric...

Hi. Just started to get an F3 Fan Fault on this boiler. On power up there seems to be a quiet thump from somewhere then it goes through the start up sequence. It spends a few seconds on the ‘c’ display before coming up with the F3 error code. Can anyone advise...
HI, we have replaced 3 manifolds (1 upstairs 2 downstairs) with new Warmup units. The installation manual from Warmup states that to fill the system you have to fill each circuit in turn using the fill / drain points on each manifold. However, my plumber said that he always uses the filling loop...
My heat only gas boiler is drained from the boiler drain valve - There is no water in the F&E tank. The hot water vented cylinder is removed. So far so good
Twice this evening I heard radiator gurgling noises which frightened the life out of me
I cant seem to reproduce the noise and I cant get...
