How to choose a trustworthy solar heater installer

Choosing the installer matters to your solar heater experience as much as choosing the model itself — maybe more. A great heater installed wrong performs poorly, and a company that vanishes after the sale leaves you on your own if something breaks. Here are 5 things to check before paying any deposit — without naming or comparing specific companies. The goal is knowing what to ask.

1. Is the product genuine and authorized, or a copy?

Ask about the authorized agent for the product and its source. Genuine products come with a real warranty from the manufacturer; copies usually show their weaknesses later (scale buildup, weak heating) once any warranty has run out — or never existed.

2. Is there an inspection before the final price?

A serious company inspects your roof and determines the right capacity and spot before giving you a final price — not selling the same model to every home. If someone quotes you a price over the phone without seeing your roof, that's a red flag.

3. Is the warranty written, not just spoken

Ask: how long is the warranty? What exactly does it cover (the tank? the panels? the backup element?)? And is it written in an invoice/formal contract, not a verbal promise.

4. Does after-sales service actually exist

Ask: if something breaks after a year, who do you call? Companies that disappear after the sale save you money upfront and cost you more later.

5. Ask to see real installations, not stock photos

Ask to see real completed projects, not photos from the internet. It's the fastest way to confirm the company has actual field experience.

So what do I do now?
