Ideal vs Glow-worm: Boiler comparison

We’re going to be putting the Ideal Logic Max range up against the Glow-worm Energy to help you in your decision making when it comes to finding a new boiler. Both of these ranges include gas-fired combi, system and regular available in a number of outputs.

Combi boilers: Ideal Logic Max vs Glow-worm Energy

A combi boiler is the most popular boiler type in the UK. They deliver instant heating and hot water on demand as and when it’s needed, removing the need for any additional tanks or cylinders.

Boiler Output Ratings Seasonal Space Heating Energy Efficiency Warranty
Ideal Logic Max Combi Boiler Range
Logic Max C24 24 kW 94% 10 Years
Logic Max C30 30 kW 94% 10 Years

The Ideal Logic Max is a market leading combi boiler that’s highly efficient and covered by a lengthy 10 year warranty:

  • Boiler frost protection will see that the unit is protected during periods of freezing cold weather
  • A low lift weight and compact dimensions help to make installation easier, potentially reducing costs
  • A large digital display is user-friendly, offering more control
  • Fitted with an aluminium heat exchanger that can be kept preheated which increases the speed of hot water delivery
  • Covered by an extensive warranty of 10 years

The Glow-worm range of Energy combi boilers comes with an almost identical number of output ratings to the Ideal Logic Max range, giving you a great selection. The Energy range does fall short of the Logic Max in terms of efficiency and warranty but there are a number of warranties to make them well worth considering:

  • Quiet Mark accredited as it’s ultra-quiet during operation
  • Option of top and rear flue which offers more flexibility with the installation
  • An aluminium heat exchanger that has been designed for a long life and can help to lower energy bills
  • Innovative 4-sided cooling reduces stress on the heat exchanger, helping to greatly reduce the risk of an issue
  • Compact dimensions mean the unit can fit within a standard cupboard
  • Fitted with a modulating Grundfos pump that adapts to the demand for heating and hot water which will help to further reduce bills

System boilers: Ideal Logic Max vs Glow-worm Energy

A system boiler includes a hot water cylinder that stores domestic hot water but takes water from the mains rather than a tank in the loft.

The Ideal Logic Max range of system boilers is one of the most efficient, reliable and effective heating systems available on the market. As well as being covered by an extensive 10 year warranty, they also boast:

  • The heat exchanger also has wide waterways which is ideal for retrofit installations
  • Ultra-quiet performance during operation has seen Energy boilers earn a Quiet Mark accreditation
  • Compact dimensions allow the units to fit within a standard kitchen cupboard
  • A modulating Grundfos pump is able to meet the heating and hot water demands without using too much energy, helping to keep energy bills down to a minimum

Regular boilers: Ideal Logic Max Heat vs Glow-worm Energy

Regular boilers are best suited to large older properties as they tend to have the suitable pipework in place. In addition to the unit, you will also need a hot water cylinder as well as a feed and expansion tank in the loft.

Efficiency

Both the Ideal Logic Max and Glow-worm Energy are efficient boiler ranges that could help to lower your energy bills. To help deliver increased efficiency, Ideal Logic Max units are fitted with a brass system filter while Glow-worm Energy boilers have an automotive grade aluminium heat exchanger.

Potential cost

In terms of cost, Glow-worm Energy boilers are definitely the cheapest but this is to be expected as Ideal are one of the leading boiler manufacturers. The only time you’re likely to find a Glow-worm Energy boiler hit a higher price tag than it’s Ideal equivalent is when it comes to the more powerful combi boilers.

Boiler Type Ideal Boiler Potential Cost Glow-worm Boiler Potential Cost
Combi £1,015 – £1,248 £550 – £1,580
Regular £875 – £1,060 £710 – £870
System £915 – £960 £725 – £860

So if you’re looking for a boiler on a tight budget then a Glow-worm Energy unit is probably the best option.

Warranty

While, more often than not, the Glow-worm Energy range is likely to be the cheaper option, it’s important to consider the warranty. An additional 3 years is available with the Ideal Logic Max range over Glow-worm Energy boilers (10 years compared to 7 years).

This can give you an indication of how long the manufacturer believes the boiler will perform at its most effective and efficient. So while you might be saving money with an Energy boiler, there’s a chance that you might be faced with replacing it sooner than if you’d had a Logic Max installed.

In terms of what’s covered by the warranty, Ideal will see that you’re covered for any mechanical or electrical breakdowns that are caused by defective workmanship – the same can be said of Glow-worm warranties. In both cases you will need to register the boiler with the manufacturer within 30 days to begin the warranty.
