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 Combi2 24 | 24.2kW max hot water | 9.9 l/min at a 35 degree rise | 47-349-93 |
| Logic Combi2 30 | 30.3kW max hot water | 12.4 l/min at a 35 degree rise | 47-349-94 |
| Logic Combi2 35 | 35.3kW max hot water | 14.5 l/min at a 35 degree rise | 47-349-95 |
Case size: 700 x 395 x 278mm (combi casing). Weight: 28.5 to 28.6kg lift weight.
- 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. On central heating all three run at 2.512 m3/h, because the heating input is capped across the range. Ideal calculates these at a gross calorific value of 38.7 MJ/m3.
- The standard Logic carries 2 years parts and labour plus 10 years on the heat exchanger, and no filter in the box. The Logic Max shares these outputs and flow rates exactly.
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. It is the identifier to trust when a badge has faded.
Reading the plate
Worth knowing on site
- Typically the entry warranty tier in Ideal's line-up.
- Available in combi, system and heat-only variants, confirm which from the data plate.
On the tools
As Ideal's entry-tier range, the Logic is a common sight on cost-conscious replacements where the customer wants a straightforward gas swap rather than smart controls. Its position as the base warranty tier is usually the first thing worth flagging when quoting against a Logic Max.
Variants and configuration
It spans combi, system and heat-only formats, giving the Logic a broad footprint across job types despite being the budget tier. Because the configuration varies so much across that spread, confirm it from the data plate rather than assuming from the model name alone.
Where it sits in the range
The Logic sits at the base of Ideal's current domestic line-up, below the mid-range Logic Max and the premium Vogue Max. It is typically the range fitted when price is the deciding factor over the longer warranty or extra features of the tiers above it.
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.
