A boiler company's logo spends most of its life very small: on a service sticker inside a mechanical room, at the top of a quote, as a round icon beside your Google reviews. We design for those sizes first and enlarge from there, so the mark still reads when it matters most. You receive clean master files, colour values for every medium, and a short rulebook that keeps suppliers consistent.
Who this is for
- Established boiler and hydronic companies whose mark exists only as a low-quality image or an old sign-shop file.
- Companies that have grown from one van to several and now see three slightly different versions of the logo on the road.
- New companies or divisions that have finished naming and cleared the name with their lawyer.
- HVAC firms adding a boiler division that needs to feel related to the parent brand without copying it.
What is included
The mark
A primary logo, a compact version for tight spaces, and a square icon. Each is tested at the width of a thumbnail and at the height of a van panel.
Colour
A small palette with values for print (CMYK and spot), screen (hex) and vinyl film references your installer can match. We check contrast so the name stays readable on white vans, dark uniforms and phone screens in sunlight.
Type
One or two typefaces chosen for legibility on invoices, websites and vehicles, with licensing noted so nobody receives a surprise bill later.
The rulebook
A short document, not a 60-page manual: clear space, minimum size, colour do's and don'ts, and examples on a sticker, a shirt, a van and a quote. Your sign shop and apparel supplier should be able to follow it without calling you.
The process and timeline
- Audit (week 1). We gather every place your current brand appears, from stickers to the fleet, and photograph the inconsistencies.
- Directions (weeks 2–3). A few distinct routes, each shown on real applications, not floating on a white page.
- Refinement (weeks 3–5). One route, tightened through two rounds of feedback.
- Files and rulebook (week 5–6). Final masters, colour specifications and the rulebook.
Timelines stretch when approvals involve several partners, so we agree a decision-maker at the start.
How we judge the result
We use practical tests rather than taste alone:
- The sticker test. Printed at the size of a real service sticker, is the company name readable at arm's length?
- The icon test. At the size of a Google Business Profile icon, does the mark still look like you, or like a smudge?
- The one-colour test. Embroidered in a single thread colour, or cut from one vinyl colour, does it still work?
- The distance test. On a van mock-up viewed from across a street, can a stranger read the name?
Once the identity is live, we watch branded searches and whether calls mention the company correctly, as part of any marketing plan.
Mistakes to avoid
- Fine detail. Thin lines, small taglines and gradients disappear in embroidery and on stickers.
- Too many colours. Every extra colour costs money on vinyl and thread, and increases the chance a supplier gets it wrong.
- Copying the market leader in your town. Looking like a competitor sends your awareness to them.
- Approving on a laptop only. Always print a sticker-sized proof and look at it in a dim room.
- Losing the files. Keep the master files in your own storage. We hand them over in full, because the brand belongs to you.
What happens next
Before the rollout, give each supplier a copy of the rulebook and keep one for yourself.
Most clients move from the logo to vehicle wraps and uniforms, and then to the rollout plan that schedules the change across everything. We design; your sign shop and apparel supplier produce. We are a branding and marketing service and never install or service equipment.
Frequently asked questions
Should the logo show a flame or a boiler?
It can, but flames and water drops are used by a great many heating and plumbing companies, so they rarely make you memorable. We explore them alongside a typographic mark and choose whichever is clearer at small size.
What files will I receive?
Vector master files, versions for light and dark backgrounds, a one-colour version, a square icon for online profiles, and colour values for print, screen and vinyl. You own all of them.
Can you redraw our existing logo rather than replace it?
Yes. If customers recognise the current mark, a careful redraw keeps that recognition while fixing thin lines, bad spacing and missing files.
How many concepts do we see?
We present a small number of distinct directions with reasoning, then refine one. Fewer, better-argued options lead to faster decisions than a wall of variations.
