Specifications
Match the badge in front of you to a row before you use any of this. Every figure below was read from the Ideal Heating literature listed under Sources at the foot of this page, checked 6 September 2026. Outputs, variants and part numbers change by year, so the appliance data plate is still the last word.
| Variant | Output | Hot water flow rate | GC number |
|---|---|---|---|
| Logic Max Combi2 24 | 24.2kW max hot water | 9.9 l/min at a 35 degree rise | 47-387-03 |
| Logic Max Combi2 30 | 30.3kW max hot water | 12.4 l/min at a 35 degree rise | 47-387-04 |
| Logic Max Combi2 35 | 35.3kW max hot water | 14.5 l/min at a 35 degree rise | 47-387-05 |
Case size: 700 x 395 x 278mm (combi casing). Weight: 28.5 to 28.6kg lift weight.
- The Logic and Logic Max combis run off the same technical specification. The Max premium buys an Ideal System Filter in the box and 10 years parts and labour, not a hotter tap.
- Gas rate at maximum hot water is 2.512 m3/h on the 24, 3.135 on the 30 and 3.657 on the 35, all at a gross calorific value of 38.7 MJ/m3. On central heating all three run at 2.512 m3/h.
- Ideal requires the boiler and its included filter to be registered together, within 30 days of installation, or the cover drops to 12 months.
Where the data plate is
Ideal prints the GC number on the data plate and calls it the Benchmark number in the manual, so the two are the same figure. The GC numbers differ from the standard Logic, so the plate still tells you which tier is fitted.
Reading the plate
Worth knowing on site
- Compact and light, often chosen for tight kitchen-cupboard swaps.
- Higher warranty tier than the standard Logic when installed to the manufacturer's terms.
On the tools
Sitting a step above the standard Logic, the Logic Max is often the compromise pick: a longer warranty and a bit more feature set without moving up to Vogue Max pricing. Its compact, light build is regularly mentioned as a reason it gets chosen for tight kitchen-cupboard swaps.
Variants and configuration
Like the standard Logic, it covers combi, system and regular formats, so the same care over configuration applies on site. The main practical difference from the base Logic is warranty length rather than a wider output spread, so check the terms as much as the data plate.
Where it sits in the range
The Logic Max occupies the middle of Ideal's three-tier domestic range, between the entry Logic and the premium Vogue Max. It is the range Ideal positions for customers wanting more warranty confidence than the base tier without paying for Vogue Max's top-end features.
Finding the manual and the data plate
For the exact outputs, gas rate, dimensions and commissioning figures, work from the appliance’s data plate and the manufacturer’s installation and servicing instructions. The GC (Gas Council) number and serial are on the data plate, usually behind the front panel or on the underside. Ideal Heatingpublishes its manuals and support at Ideal Heating support.
