When it comes to choosing between a combi or conventional boiler, many homeowners in Bath and across Somerset find themselves scratching their heads. It’s one of the most common questions we get asked during our callouts from customers looking to get a new boiler in Bath, and with good reason – selecting the right heating system for your home is a significant decision that impacts your comfort, energy bills, and property value for years to come.
At GreenSmart Services, we’ve installed hundreds of both combi and conventional boilers throughout Bath, giving us first-hand experience of which systems work best in different homes. Today, we’re sharing our practical knowledge to help you make an informed choice.
Understanding the Basics: Combi vs Conventional
Before diving into which is better, let’s be clear about what we’re comparing:
Combi (Combination) Boilers
A combi boiler provides both heating and hot water directly from one unit, without needing separate water tanks or cylinders. When you turn on a hot tap, cold water flows directly from the mains through the boiler, where it’s heated instantly.
Conventional (Regular) Boilers
A conventional boiler works alongside a cold water tank (usually in the loft) and a hot water cylinder (often in an airing cupboard). The system heats water and stores it for when you need it.
When a Combi Boiler Shines
Combi boilers have soared in popularity over the past decade, and we’ve installed numerous Worcester Bosch combi boilers that homeowners absolutely love. Here’s where they excel:
Perfect for Smaller Properties
If you’ve got a modern flat, terrace, or small semi in Bath, a combi makes brilliant use of limited space. Without the need for water tanks or cylinders, you’ll free up valuable storage space – perhaps that airing cupboard could become a handy pantry instead?
Ideal for Lower Hot Water Demands
For couples or small families who don’t typically use multiple hot water outlets simultaneously, combi boilers provide excellent efficiency. One of our customers, a professional couple in Oldfield Park, switched from a conventional to a Worcester Bosch combi boiler and were delighted with the improved performance and reduced energy bills.
Energy Efficiency Advantages
Modern combi boilers only heat water when you need it, eliminating the heat loss associated with storing hot water. This means lower energy usage and reduced bills – something we all appreciate in today’s economic climate.
When Conventional Boilers Work Better
Despite the rise of combi boilers, conventional systems remain the better choice in specific circumstances. We still install many conventional boilers across Bath, particularly in certain types of properties:
Superior for Larger Properties
If you’ve got one of Bath’s beautiful Georgian townhouses or a larger family home in Lansdown or Widcombe, a conventional boiler often performs better. These systems can supply hot water to multiple bathrooms simultaneously without any drop in pressure or temperature.
Better with Low Mains Pressure
Some areas around Bath have fluctuating or low water mains pressure. In these locations, conventional systems often deliver more reliable performance since they’re not dependent on mains pressure for operation.
Works with Older Heating Systems
If your home has an older radiator system, particularly one with narrow pipes, replacing like-for-like with a conventional boiler often causes less disruption. During a boiler replacement, we can often connect to your existing pipework with minimal alterations.
Considerations Beyond the Boiler Type
When advising our Bath customers on choosing between a combi or conventional boiler, we always consider these additional factors:
Water Usage Patterns
How does your household use water? A family with teenagers who all shower in the morning might find a conventional system with a well-sized cylinder more appropriate than a combi.
Future-Proofing
Planning home extensions or additional bathrooms? These changes might affect which system works best long-term. We’ve had several customers in Bathwick and Combe Down who opted for conventional systems when planning home expansions.
Available Space
While space considerations usually favour combi boilers, some modern conventional systems have become quite compact. The Worcester Bosch Greenstar range includes conventional boilers that take up surprisingly little space while delivering exceptional performance.
Energy Efficiency Goals
Both systems can be highly efficient when properly specified and installed. During a professional boiler service, we can advise on optimising either system type for maximum efficiency.
The Verdict: No One-Size-Fits-All Answer
The truth about whether a combi or conventional boiler is better? There’s no universal answer. The right choice depends entirely on your specific property, household needs, and preferences.
This is why we always conduct a thorough assessment before recommending boiler types to our customers. Our survey provides a comprehensive evaluation of your home’s heating requirements, ensuring you get the perfect system.
What About System Boilers?
As a quick aside, system boilers offer something of a middle ground – like conventional boilers but without the need for a heating system water tank in the loft. For some properties in Bath, particularly those with loft conversions but multiple bathrooms, a system boiler can be the ideal solution.
Don’t Forget About Aftercare
Whichever type you choose, proper maintenance is crucial. Annual servicing ensures your new boiler remains efficient and reliable year after year.
