Thermann 270L Heat Pump

Review

Performance & Efficiency

The Thermann 270L is a larger-tank, all-in-one hot water heat pump that Reece has just brought to the New Zealand market under its own Thermann brand.

With 270 litres of storage it's built for larger households — Reece rates it for homes of up to seven people — where the priority is plenty of hot water and a smaller power bill than a conventional electric cylinder. We would typically recommend a 300L+ cylinder for 5 or more people in a household, particularly if you are high water users or coming off instant gas hot water.

Reece quotes a coefficient of performance of 4.7 and running-cost savings of up to 73.1% against a standard electric cylinder. With the low GWP R290 refrigerant now standard in most NZ integrated units. Those are manufacturer figures, tested to AS/NZS 5125.1:2014 at a mild 19°C — a warmer air temperature than much of the country sees in winter, when a heat pump works hardest and this efficiency will be lower.

Features

The −5°C to 43°C operating range covers the vast majority of New Zealand conditions, and an electric backup element steps in on the coldest mornings.

The warranty is a genuine strength: five years on the cylinder and five years on the refrigeration components including labour — and because labour is usually where a heat-pump claim gets expensive.

It's outdoor-only, and at just over two metres tall, placement under eaves or on a deck needs checking. Several specs we'd normally publish — operating noise, first-hour hot water delivery, recovery rate and installed price — aren't stated on Reece's documentation yet, so we've left them pending rather than guess. As a new entrant with a strong warranty and a future-proof refrigerant, it's a promising option for larger households; we'll firm up our rating once the noise, output and independent efficiency numbers are confirmed.

Supply and Service Support

Thermann is a Reece product, designed and manufactured in Australia. Meaning it's backed by one of the country's largest plumbing-supply networks, so parts, service and trade support should be easy to come by.
