Most jobs we do are unique and we treat every installation individually but there is a process that we follow that we find helps. 

 

Calling about honeywell evohome.jpg

As soon as you call us, we’ll ask you a few questions about your current heating and hot water system.

-       Do you have any pre-existing issues with your heating and hot water?

-       What types of radiators and valves do you have?

-       Do you have any underfloor heating?

-       How to you currently control your heating system

-       And most importantly, what would you like to be able to achieve with a Honeywell evohome?

We’ll probably ask you to take some photos of the current system so that we can check compatibility with Honeywell evohome. This usually means that a home visit is not required but we’re more than happy to visit if you’d prefer.

We’ll then draw up a proposal for you. This will include suggestions for how many zones you should have in your house and any of the fixtures and fittings you many need, plus any additional work that may be needed to make the current heating system compatible with Honeywell evohome. 

Normally it takes a day to install the full Honeywell evohome system. If the system is more complicated or very large then it may take two days but we will always inform you ahead of time if this is the case.

Typically we’ll arrive to start work on the evohome installation at 8am. 

First we’ll drain the system. Whilst the system is drained we’ll check all the valves and any additional components on the system, if we need to change any we’ll do this whilst the system is empty. 

Some of the most typical modifications we need to fix or fit are: 

-       Radiators that do not have TRVs (Thermostatic Radiator Valves) or radiators that are leaking.

-       No bypass fitted which is essential for safe, quiet and efficient running of the evohome system

-       Fit TRV to towel rails so that they can be controlled by evohome

-       Alter some of the heating pipework or remove motorised valves and other unnecessary components.

Once we have carried out our modifications we’ll then refill the system and treat it with a corrosion inhibitor.

Now your system is ready and we can start work on the controls

First, we'll remove the existing controls and wiring centre and replace them with the new Honeywell evohome components (relays, stats, control panel(s), valves and safety devices). If you have a system that has multiple pumps we can fit a component to separate them so that only the pumps that are needed turn on rather than all of them, all the time, as we so often see.

Any underfloor heating controllers and any relays will be mounted and wired into the manifold. We then fix any new thermostats to the walls and fit HR92 radiator valves.

At this stage we configure and bind together the new Honeywell evohome system. We'll stress test the system and check for any communications faults or bad binding.

Having connected your system to the evohome servers via Wi-Fi, we’ll assist you in setting up an account, installing the app onto your devices and then give you a full handover to run through the system and how it works.

Finally, we’ll remove any of our rubbish from your house and leave things as tidy as we found them. 

We would expect to be on our way by 6pm, maybe 8pm if the system is on the bigger side.

Depending on the size of your system we’ll often be able to do a boiler and/or ‘megaflow’ service whilst on site at no additional charge.
