New Boilers for Marshalswick and Jersey Farm

Most homes in Marshalswick were built after the war, from the semis and terraces around The Ridgeway and Sandpit Lane to the later houses of Jersey Farm. Many have already had one or two boilers, and plenty still have the original arrangement of a hot water cylinder in the airing cupboard and cold water tanks in the loft.

That leads to the question most homeowners here need answering first: stay with a cylinder or switch to a combi? It depends on how many people live in the house, how many showers run at once and the water pressure coming into the property, so we measure the pressure and flow before we recommend anything.

Because we are based on Lemsford Road, Marshalswick is on our doorstep. If anything needs adjusting after the installation, or the boiler is due its first annual service, we are close by. For other plumbing and heating work nearby, see our Marshalswick plumbing and heating page.

Combi or Cylinder: Choosing for Your Home

Here is how the main options usually work out in Marshalswick homes, and what else goes into a good installation.

Combi Conversion: Removing the loft tanks and cylinder frees up the airing cupboard and gives mains pressure hot water, as long as the incoming supply is strong enough for your household.
Keeping a Cylinder: In a family home with two bathrooms, a system boiler with an unvented cylinder can run two showers at once without the drop you can get with a combi.
Gas Supply Sizing: A larger combi needs more gas than the boiler it replaces. We check the gas pipe from the meter can carry it, because an undersized pipe is a common reason new boilers underperform.
Hard Water: St Albans water is hard, so we fit scale protection where the regulations call for it and a system filter to protect the new boiler.
The Right Controls: In England a new combi has to be fitted with an energy saving control, such as a smart thermostat with automation or weather compensation. We explain which option suits the way you use your heating.

When Your Boiler Is Due for Replacement

Boilers rarely give much notice in the middle of winter. These are the signs it is time to plan a replacement rather than wait for a breakdown.

Parts Getting Hard to Find

When an engineer has to order parts for an older model, or tells you they are no longer made, every breakdown takes longer and costs more to fix.

Hot Water That Runs Out

If the cylinder runs cold halfway through the morning showers, the household may have outgrown the system. A combi or a larger cylinder can solve it.

Rising Gas Bills

Older non-condensing boilers send much of their heat up the flue. A modern condensing boiler can make a noticeable difference to running costs.

Kettling and Banging

A kettle-like rumble inside the boiler is often limescale on the heat exchanger, a common problem with St Albans water. On an older boiler it is usually the start of the end.

Boiler Installations We Carry Out in Marshalswick

These are the types of boiler installation we carry out across Marshalswick and Jersey Farm.

Combi Boiler Swap

Replacing an existing combi with a new one, usually in the same position so the flue and pipework can be reused where they are sound.

Tank to Combi Conversion

Taking out the loft tanks and cylinder, capping off the old pipework and fitting a combi, with the space handed back to you.

System Boiler and Cylinder

For larger households, a system boiler with an unvented cylinder that keeps strong pressure at every tap.

Like-for-Like Conventional

Where you want to keep the tanks and cylinder, we replace the boiler and check the tanks, pump and valves at the same time.

Smart Controls Upgrade

A new thermostat or app control fitted with the boiler, so you can manage your heating from your phone.

Boiler Relocation

Moving the boiler from a kitchen wall to a cupboard, utility or loft, with the flue and condensate pipe rerouted to suit.

 Trustindex verifies that the original source of the review is Google. Really happy with the work carried out by Alban Plumbing and Heating. They fitted several new radiators in my home and the whole process was smooth from start to finish. They arrived on time, were friendly and professional, and took great care while working in the house.
The installation was completed to a high standard, everything was left clean and tidy, and the new radiators look fantastic and heat up perfectly. It's refreshing to find a company that is reliable, communicates well, and clearly takes pride in their work.
I wouldn't hesitate to use Alban Plumbing and Heating again and would happily recommend them to friends and family.

He also recently attended in under an hour to fix an emergency leak that he and his son sorted with great efficiency allowing us to get back to work and continue operating with minimal disruption to our business and patients. He’s reasonably priced and friendly and I’m sure we will be using him for many years to come.  His 5 star status is well deserved.

Marshalswick Boiler Installation: Questions Answered

Can I have a combi if my house has loft tanks?

Usually, yes. We check the incoming water pressure and flow first. If they are good enough for your household, we remove the tanks and cylinder and fit a combi. If not, a system boiler with an unvented cylinder may suit you better.

How long will I be without heating?

A straight combi swap is normally done in a day. A conversion from tanks to a combi takes longer because of the extra pipework, and we confirm the timing when we quote.

Do I need to move my boiler?

Not usually. Keeping it in the same place is quicker and cheaper. If you would like it moved, for example out of the kitchen, we check where the flue and condensate pipe can go and include it in the quote.

What does a new boiler cost in Marshalswick?

It depends on the boiler, whether it is a swap or a conversion and how much pipework changes. The survey and quote are free, and the price is agreed before work starts.

Will the installation be registered?

We notify the installation as the Building Regulations require, and we explain what the manufacturer needs from you to keep the warranty valid, which usually includes an annual service.

Do you cover Jersey Farm as well?

Yes. We cover Marshalswick and Jersey Farm in AL4, including Sandpit Lane, The Ridgeway and the roads around The Quadrant.
