What Type of Boiler is Best for Your Home? Complete Comparison Guide

When you’re searching for a heating engineer in Tavistock to install a new system, one of the first questions we’re often asked is: “What type of boiler should I choose?” It’s an important decision that will affect your home’s comfort and energy bills for years to come. At GasJack, we’ve installed thousands of boilers across the Southwest, and we’re here to help you understand your options.

The Three Main Boiler Types

Modern domestic boilers generally fall into three categories, each with distinct advantages depending on your home and lifestyle:

1. Combi Boilers

Combination boilers provide both heating and hot water directly from one unit, without requiring separate water tanks.

Ideal for:

  • Smaller properties with limited space
  • Homes with 1-2 bathrooms
  • Properties with good water pressure
  • Households with modest hot water demands

Advantages:

  • Space-saving design (no tanks required)
  • Hot water on demand
  • Economical to install
  • Efficient operation with minimal heat loss

Limitations:

  • May struggle if multiple showers/taps are used simultaneously
  • Not ideal for areas with very low water pressure
  • Less suitable for larger households with high hot water demand

2. System Boilers

System boilers work with a hot water cylinder but don’t require a cold water tank in the loft.

Ideal for:

  • Medium to large properties
  • Homes with multiple bathrooms
  • Households needing simultaneous hot water from several outlets

Advantages:

  • Can deliver hot water to multiple taps simultaneously
  • Compatible with solar thermal systems
  • Better suited to areas with lower water pressure
  • More economical than conventional systems

Limitations:

  • Requires space for a hot water cylinder
  • Hot water can run out and need time to reheat
  • Generally more expensive than combi boilers

3. Regular/Conventional Boilers

Also called traditional or heat-only boilers, these systems use both a hot water cylinder and cold water tanks in the loft.

Ideal for:

  • Older properties with existing traditional heating systems
  • Large homes with multiple bathrooms and high hot water demand
  • Properties with low water pressure
  • Homes where significant radiator use occurs simultaneously

Advantages:

  • Excellent for high hot water demand
  • Works well with very low water pressure
  • Ideal for like-for-like replacements in older properties

Limitations:

  • Requires the most space (cylinder plus water tanks)
  • Less efficient due to heat loss from stored water
  • Generally more complex and expensive to install

Choosing Based on Your Property Type

Your home’s characteristics play a significant role in determining the most suitable boiler:

For Flats and Small Houses

Combi boilers are typically the best choice, offering space-saving benefits and sufficient performance for smaller properties.

For Medium-Sized Family Homes

System boilers often provide the ideal balance, offering good hot water capacity without requiring loft space for tanks.

For Large Properties

Regular/conventional systems or larger system boilers typically work best, especially if you have multiple bathrooms in use simultaneously.

Energy Efficiency Considerations

Modern boilers of all types are considerably more efficient than older models, with most achieving A-rated efficiency. However, there are still differences worth noting:

  • Combi boilers often achieve the highest efficiency ratings for smaller properties
  • System boilers with well-insulated cylinders offer excellent efficiency
  • Regular boilers typically have slightly lower overall efficiency due to heat loss from stored water

A new A-rated boiler could save you up to £300 annually compared to an older G-rated system, making the upgrade cost-effective over time.

Additional Factors to Consider

Future-Proofing

Consider your future plans. Will your family grow? Might you add an extension or another bathroom? These factors could influence your choice toward a system or regular boiler even if a combi seems sufficient now.

Water Pressure

If your property suffers from low water pressure, a conventional system might be necessary. Your heating engineer in Tavistock can test your pressure during a consultation.

Compatibility with Renewables

If you’re considering solar thermal or other renewable technologies in the future, system and regular boilers work best with these additions.

Making Your Final Decision

At GasJack, we recommend having a qualified heating engineer assess your property before making your final decision. Our experts can conduct a thorough evaluation of your home, considering:

  • Your household’s hot water usage patterns
  • Available space for components
  • Water pressure in your area
  • Energy efficiency goals
  • Future-proofing requirements
  • Budget constraints

By weighing all these factors, we can recommend the perfect boiler type for your specific circumstances.

Jack & the Gas Jack Team

Jack took the time to meet with us to understand what was required and the urgency of finding a resolution to our ongoing Sports Centre and Swimming Pool issues. Jack was able to offer varying designs and solutions at different costings ensuring that all of the options were covered and explained fully regarding output and capability to determine what was best for the University.

When undertaking a large plant room refit for the sports centre and swimming pool, Jack and the team swiftly and professionally decommissioned and removed the dated Rehema, Andrews boilers and flue system.

They supplied and fitted 4 x 150kw Viessmann boilers into a bespoke cascaded system to enable the swimming pool plate heat exchanger and the heat load of the sports centre building to be run alongside each other without issue.  The new cascade flue system was installed to service the replacement Viessmann Vito-Cell 1000 litre cylinder, to allow instant hot water demand was provided and covered all areas. There was a huge amount of associated products and works required and these were carried out to ensure the whole plantroom, heating and hot water system was set up to be controlled via the new BMS.

Working with GasJack has been a joy.

Jack and his team are helpful and considerate, putting the customer first at all times.
