Ideal Logic vs Logic Max vs Vogue Max: which suits which home

By Jordan Valentine-Dunn, Gas Safe registered engineer · 15 July 2026

Three Ideal Heating wall-mounted boilers side by side representing the Logic, Logic Max and Vogue Max ranges

Ideal Heating's domestic line-up splits into three tiers. The Logic is the entry range for cost-conscious swaps. The Logic Max adds a longer warranty and a bundled system filter for the same style of job. The Vogue Max is the premium tier, with the system version suited to larger homes. The data plate, not the badge, decides the job.

What is the Ideal Logic best for?

Cost-conscious replacements in small to medium homes. The Logic is Ideal's entry tier, sold as combi, system and heat-only, with the combi in 24kW, 30kW and 35kW outputs. It is compact and light, which is why it turns up so often in tight kitchen-cupboard swaps, and it keeps the quote competitive when the customer is buying on price. What it gives up against the Max ranges is warranty length, so if the customer plans to stay in the property, it is worth pricing the step up before they decide.

What does the Logic Max add?

A longer warranty and a bundled filter on what is otherwise a familiar Logic install. The Logic Max combi comes in the same 24kW, 30kW and 35kW outputs, with system versions from 15kW to 30kW and heat-only versions below that for cylinder jobs. Ideal covers the Max with a 10 year parts and labour warranty when the boiler is registered within 30 days and serviced annually, and ships it with the Ideal System Filter, which is a condition worth explaining to the customer at quote time. For most one and two bathroom homes it is the sensible middle pick.

When do you reach for the Vogue Max?

Larger homes, higher hot water demand, or a customer who wants the top of the range. The Vogue Max combi steps up to 26kW, 32kW and 40kW outputs, and the system version runs from 15kW to 32kW, which is where homes with three or more bathrooms and a decent cylinder belong. Ideal advertises up to 12 years of warranty on the Vogue Max, tied to registration windows, annual servicing and installer scheme terms that have changed between generations, so check the current conditions rather than promising a customer a number. Build quality and components sit a tier above the Logic family, which is the honest pitch for the price difference.

What to check before you quote

  • The data plate: read the exact model and output from the appliance, not from the customer's paperwork or an old invoice.
  • Hot water demand: bathrooms and simultaneous use decide between combi and system, and between the 30kW and 35kW Logic sizes.
  • Warranty conditions: registration windows, annual servicing and filter requirements differ by tier, so check Ideal's current terms.
  • Siting: all three ranges are compact, but confirm clearances and the flue run against the installation manual for the exact model.
  • The existing system: a heat-only Logic or Logic Max may be the right like for like swap on an older vented system with a cylinder.

Only a Gas Safe registered engineer can size, install and certify a boiler. This is general guidance, not a substitute for the manufacturer's manual or your own on-site judgement.

Boiler reference

Whichever tier goes on the wall, the paperwork is the same job every time. Manifold builds the CP12 and service record from the check on your phone, reads the make, model and GC number off the data plate with PlateScan, and keeps the property's appliance history ready for the next visit.

Frequently asked

Which Ideal boiler is best for a small home?

For a one-bathroom home with ordinary hot water demand, the Logic or Logic Max combi in 24kW or 30kW is usually the sensible pick. The Logic keeps the price down and the Logic Max adds a 10 year warranty and a bundled system filter. Base the sizing on the property's measured demand and the data plate rather than the badge.

What is the difference between the Ideal Logic and the Logic Max?

They share the same combi outputs of 24kW, 30kW and 35kW and a similar compact install. The Logic Max adds a longer parts and labour warranty, conditional on registration within 30 days and annual servicing, and ships with the Ideal System Filter. The standard Logic sits on a shorter warranty as the entry tier.

Is the Vogue Max worth the extra money over the Logic Max?

For larger homes, high hot water demand or customers who want the longest cover, often yes. The Vogue Max combi reaches 40kW, the system version suits homes with three or more bathrooms, and Ideal advertises up to 12 years of warranty subject to its current terms. For a modest one-bathroom swap, the Logic Max usually does the job.

Do Ideal boilers come as heat-only, not just combi?

Yes. The Logic and Logic Max ranges include heat-only versions for homes with an existing vented system and a hot water cylinder, alongside combi and system formats. Confirm the configuration and output from the appliance data plate and the installation manual before quoting a like for like swap.
