Propeller makes websites, online advertising and email promotions. We turn things around. Cause a stir. Drive customers to your business.

Try getting your plumber to explain your central heating system in a way that’s easy to understand – bet he reaches for a pencil and paper.

Heating systems are a tricky subject, even for those submerged in the business, which is why we encouraged GAH to change their website to incorporate dynamic home heating diagrams which illustrate water flowing around a property in a way that’s easily understood by all.

The moving diagrams show water flow, heat sources and the potential pitfalls such as turning on a tap when someone else is in the shower.

It’s an innovative site that plumbers love just as much as we do.
