## At a glance

- Spiral construction is offered for two stated flue inner dimensions: 12.5 cm and 15.5 cm.
- The listing describes a stainless-steel tube with a 1/2 inch water connection.

## Before you buy

- The listing is inconsistent about dimensions: product details give 15 x 15 x 40 cm, while the description lists 15 × 15 × 40 cm / 18 × 18 × 40 cm alongside the two flue sizes. Confirm the selected variant, dimensions and included components in the chosen listing. The manufacturer also advises avoiding direct flame contact, emptying the coil completely before frost, checking regularly for leaks and damage, and installing only outside electrical wiring.

## A good fit for

- Fireplace or wood-stove owners seeking to preheat water using residual flue heat.
- Buyers whose flue inner dimension and water connection match the selected coil.

## Less suited to

- Buyers who need a confirmed fit without first matching the selected variant to their flue.
- Those looking for a specified water-heating output or independently verified performance, which the supplied listing does not establish.

## Customer feedback

The supplied evidence contains only a very small set of aggregate ratings, all in the five-star category. That is a limited positive signal, not enough to establish performance, fit or long-term reliability. For this coil, buyers should still confirm their flue size and connection against the listing.
