Combi Boilers in Ayrshire – Should I switch?

Combi Boilers in Ayrshire – Should I switch?

Combi boilers have seen a surge in popularity across Ayrshire and beyond in recent years. Our customers regularly come to us asking the differences between regular boilers with a hot water cylinder and combi boilers and whether it’s worth switching. We felt that now would be a good time to answer some of the common questions we get about combi boilers!

What is a Combi Boiler?

The “combi” in the name is short for combination, and that’s because this type of boiler serves two functions: heating your home and providing hot water. A regular boiler makes use of tanks of hot and cold water, which will be distributed as you need them. However, the combi boiler does not require the storage tank. When you turn the hot water tap, the combi boiler ignites and provides you with all the hot water you need.

Advantages of a Combi Boiler vs Regular Boiler

Combi boilers come with a number of advantages over their more conventional counterparts. Firstly, combi boilers are much better suited to smaller homes or flats. This is because a combi boiler uses up a lot less space. By freeing yourself from the various water tanks, a lot more space becomes available in your home. With space at a premium, this goes down as a big win for the combi boilers.

Because they are smaller, they are generally more cost efficient when it comes to installation too. Not only are they more cost efficient, but they require less time to install for engineers. So while your neighbour is waiting around for their regular boiler to be installed, you can have your new combi boiler up and running in much less time.

In terms of energy efficiency, combi boilers once again come out on top. This is because the boiler will only heat up water when you request it, i.e. when you come to do the dishes, wash your hands or go for a shower. Traditional boiler systems, on the other hand, will normally heat water a couple of times per day. Once the water is heated it is then stored in the hot water tank waiting to be used.

In situations when the water is heated but not used, this represents a great waste of energy. In this day and age, it’s becoming more and more clear that we cannot afford to waste energy; efficiency is key.

How Much is a Combi Boiler?

The cost of a combi boiler depends on a few factors, such as your home, the type of boiler you want etc. Get in touch with us today and we can give you a quote on a brand-new combi boiler. Generally speaking, a combi boiler will cost you less than a traditional condensing boiler.

Commercial Installation Project

Commercial Installation Project

Our team have been well travelled in recent weeks with a trip across the border to install a heating system for a client at their new facility in Barnsley.

Project Background

The client had recently purchased a new manufacturing facility which was to under go a complete refurbishment to serve a dual purpose as workshop with a office area to accommodate staff.

Existing Heating System:

The office heating was supplied through radiators that had individual thermostats and appeared to be in reasonable condition as was the pipework, the boiler and pump feeding same is non-operational, obsolete and required to be replaced.

The existing hot water boiler was a gas fired unit, while operational was leaking and obsolete.

The factory unit had no heating as four of the five existing air heaters having at some point been dismantled and were lying on the ground. Again these heaters were obsolete, probably 20-years old and even if they were reinstalled should the customer have required any parts for same they would be difficult if not impossible to obtain and the operation of the system would be of poor efficiency.


Office area:
A wall mounted Keston boiler was installed with a welded low loss header arrangement which was fabricated off site. Pipework was taken from the boiler, in copper to same at a L.L.H. thereafter the pipework taken and connected to the existing heating pipes with a new circulating pump fitted.

Hot water was supplied via a 125L model of Sadia unvented cylinder, heated via an indirect coil from the Keston boiler L.L.H. with pipework via a motorised valve and pump.

Overall control over the heating/hot water was via a programmer located at boiler.

Gas pipework was rerouted and reconnected to suit, tested and certified. The boiler has a unique 2-pipe flue system comprising of 2×2” MUPVC pipes that was taken horizontally to atmosphere approx. 4m, one fresh air inlet and 1-exhaust gasses.

Workshop Area:

10-off combat CMP 35 UTN ‘U’ tube radiant heaters complete with all necessary propriety support system was supplied and fitted – these units were suspended from roof structure at predetermined height (9m approx.)

The existing gas pipework system was extended to each of the aforementioned heaters, valved at each unit with the final connection being approved flexible type.

All gas pipework was pressure tested, commissioned and certified, additional isolating valves were fitted as necessary in keeping with good practice.

Control over the system was in two zones to suit Client requirement.


This was a large space to heat but within half an hour of commissioning the workshop units unit, a comfortable working environment had been achieved.

“We are delighted with our new heating system which is not only achieves the warmth we desired in both areas of the site but is easy to operate and was completed with minimal fuss and to a high standard of workmanship”
