Conventional boilers are perfect for homes with high hot-water demand or low water pressure. Reach out to Boilerhut for comprehensive installation of conventional boilers across the UK.
Conventional boilers are ideal for larger homes with several radiators and bathrooms. However, there are several other considerations, including:
Your current boiler: It’s recommended that you replace your boiler with the same type to avoid needing to make additional modifications to the pipework and other heating system components.
The layout of your heating system: A conventional boiler replacement will likely be compatible with your current layout and won’t require additional space.
How long a boiler will take to install: Regular boilers that are incompatible with your current layout will take longer to install, leaving you without hot water during the process.
Choose Boilerhut for honest, information-led service. Trust us to install premium regular boilers with manufacturer-backed guarantees today.
Ideal for large homes with high hot water demand: Conventional boilers ensure consistent water flow and pressure when hot water is used simultaneously in multiple locations. They also produce and store high volumes of heated water.
Compatibility with classic radiators: As regular boilers can handle higher water volumes and lower pressure, they’re better suited to older homes with traditional radiator systems, older pipework, and gravity-fed systems.
Backup for solar panels: Open vent boilers can be integrated with solar panels, providing a more eco-friendly and energy-efficient heating solution.
Good for low water pressure areas: For homes in areas with low mains water pressure, a conventional boiler is a practical choice because it stores hot water in a tank.
Offers a reliable backup solution: Most regular boiler systems have an immersion heater in the cylinder, which can retain hot water in case of a boiler breakdown.
Durability: With regular maintenance and servicing, these boilers can last for decades.
Scalability: Open vent boilers can be easily upgraded to support additional storage tanks or solar panels.
What Is a Conventional Boiler?
A conventional boiler, also known as a regular boiler, traditional boiler, or heat-only boiler, provides both heating and hot water for your home.
Unlike modern system boilers or combi boilers, conventional boilers rely on a cold-water tank and a hot water cylinder to function. This makes them a great choice for homes with high hot water demand, as the hot water that’s stored in the cylinder can be used by multiple taps without strain.

How Do Conventional Boilers Work?
Conventional boilers are open-vented boiler systems, meaning a feed and expansion tank supplies the central heating circuit with water. They also accommodate the expansion of water when it’s heated by the boiler. Here’s an overview of how it operates:
The feed and expansion tank (located in the loft) receives water from the mains supply and uses gravity to transfer it to the boiler.
Water circulates through the boiler, where it is heated to the desired temperature.
Heated water moves from the boiler to the hot water cylinder (essentially a hot water tank), where it is stored until you use a tap.
In addition, hot water from the boiler is transferred to your radiator, heating it. As the radiator heats up, it warms the air in your home.

7 out of 5 stars! Outstanding service from boilerhut.
From start to finish, our experience with Boilerhut was outstanding. The entire team was extremely professional, empathetic and understanding throughout the process. They communicated clearly and always checked with us before implementing any changes, ensuring that we remained fully informed and comfortable with every decision.
A very special mention must go to Paul, who was absolutely fantastic. His customer service, patience and genuine commitment to helping us could not have been better.
The speed of the service was remarkable: there was only one day between signing the agreement and having our new boiler fitted. Even after the installation, the team continued to check in with us to make sure that we were completely happy and that everything was working as expected.
Their quotation was extremely reasonable. In fact, it was the lowest we received, but this certainly did not mean compromising on quality. No corners were cut, and the work was completed to an excellent standard.
We cannot recommend Boilerhut highly enough. I would happily give them 7 stars out of 5 if Trustpilot allowed it!

I couldn't be happier with the service from Boilerhut. From the very beginning, the team was incredibly helpful, knowledgeable, and patient, taking the time to explain the different options and helping me choose the right boiler for my home. Their advice made the whole process straightforward and gave me confidence that I was making the right decision.
I chose the Viessmann Vitodens 050 30kW with the Vitotrol 100-E, and I'm absolutely delighted with it. The quality of the boiler is excellent, it's efficient, quiet, and easy to use, and the Vitotrol 100-E is a fantastic addition that makes controlling the heating simple and convenient.
If you're looking for honest advice, great customer service, and expert knowledge, I would highly recommend Boilerhut. They made what could have been a stressful decision easy from start to finish.

Boilerhut is fantastic.
My new boiler was delivered and installed within two days from order to finish.
All of the required work (including a local roofer for the flue) was arranged for me and ran like clockwork.
The fitters worked so hard and completed the install in one day.
All of my old boiler and packaging and packing was removed from site.
This was a fantastic experience and I highly recommend Boilerhut.

New Boiler, Exemplary Service.
This review is about 6 weeks old, I had a new boiler fitted 14 May 26. Didnt do it straight away as needed to let everything settle down as it important to get it right as its a lot of money to spend.
Review has 2 parts both get 5 stars,
1st Boiler Hut, easy to use great range of products sales team Paul was great and helpful, helped me choose right boiler for my needs, Viessman 100 chosen and installed. Great price not as expensive as I was fearing. So far working great, lashings of hot water always available.
2nd part, Installation Team, Cory and Ben turned up approx 0830 and got straight on it, Cory did boiler work (decommision of old boiler and installation of new boiler) whilst Ben attacked my old radiators, taking out 6 old (20 yrs plus) radiators and nasty 10mm microbore piping, replacing with 6 new radiators and new 15mm piping both under floor and surface mounting. All this work completed by 1700hrs same day, guys cleaned up after themselves removed all rubbish and old boiler and rads and pipe work. Can not praise them enough, thanks guys. I would not hesitate to recommend most highly either Boiler Hut or Cory and Ben to anyone who needs a new bolier or fitting, Thanks guys brillant.

How to Choose the Right Conventional Boiler
We know the space you live in needs to be running at its best. Here are a few factors to help you determine the perfect fit:
Size and capacity
Match the boiler size to your home’s hot water demand.
Small households (1-2 bedrooms): 9-18kW
Medium households (2-3 bedrooms): 18-26kW
Large households (4-5 bedrooms): 26-40kW
Fuel Type
Choose between gas, oil and LPG based on availability, costs, and environmental impact. Gas tends to be better for urban households as it’s usually cheaper and produces fewer carbon emissions.
Energy Efficiency
Look for models with high efficiency ratings to reduce running costs. A SEDBUK rating of “A” with 90%+ efficiency is ideal.
Installation Costs
Factor in the prices of tanks, cylinders, pipework, and other additional components, like expansion vessels. The total cost of the conventional boiler installation will also depend on the labour rates and how complicated the project is.
A conventional boiler system is a reliable and efficient solution for homes with high hot water demand. Whether you’re considering an upgrade,emergency boiler replacement, or a newboiler installation, Boilerhut will provide you with professional service and ongoing support.

We know conventional boiler installations can be confusing. Explore our answers to some of the most common questions.
What are the environmental benefits of conventional boilers?
Conventional boilers include several eco-fiendly benefits, including:
Energy-efficiency: New conventional boilers are designed to minimise heat loss, reducing overall fuel consumption.
Solar integration: Many homeowners integrate solar panels to heat water stored in the cylinder, reducing gas or oil usage.
Fewer emissions: Switching to a Quiet Mark-accredited or Trustpilot-recommended model can significantly lower your emissions, helping for a greener future and reducing your carbon footprint.
What are the disadvantages of conventional boilers?
Some potential issues with conventional boilers include:
Size requirements: They are only suitable for properties with sufficient space for a hot water storage cylinder and a cold water tank.
Waiting periods: Hot water isn’t instant and can take time to heat up once the water in the hot water cylinder is used up.
Initial costs: More expensive to install than combi boilers
Limited hot water: The size of the storage determines how extensive your supply is. When it empties, you’ll have to wait until the boiler can heat up more water.
What maintenance do conventional boilers require?
While conventional boilers last a long time, they do require some maintenance. To ensure their functionality and ongoing heating efficiency, we include:
Annual servicing: Get a registered engineer to inspect your boiler and address any issues once a year.
Monthly pressure checks: Ensure the pressure is within its recommended range (typically 1-1.5 bar).
Radiator bleeding: Removing built-up air helps to maximise heating efficiency.
System cleaning: Prevents the buildup of dirt and mineral deposits, which can lead to corrosion.
Inspection: Checking for corrosion and damage helps to prevent smaller issues from causing further damage.
Alarm tests: Ensure the carbon monoxide and other safety alarms are working.

What are the best boilers available today, and how to choose the best boiler for you? Read through our guide to see the best brands and models available today.
Viessmann vs Worcester Bosch is a debate that’s been developing for a while. Comparing different boiler manufacturers is very important when deciding on a new boiler.
New boiler costs are a bit of a mystery to most people. Boilers should last 10-15 years, some last 25, and back boilers have been known to last 50 years.
