Mitsubishi Electric launched the Versatile domestic hot water cylinder range on 3 August 2023, the company has announced. The cylinders are made in slimline and standard versions and are intended for use alongside the company's Ecodan R32 air source heat pumps1.
The range covers five capacities across two formats. The slimline models are offered at 180L and 210L, while the standard models come in 210L, 250L and 300L1. Mitsubishi Electric states that the choice of sizes allows the cylinder to be matched to a household so that it is not oversized, which it says prevents unnecessary energy consumption and reduces heating costs, and that a quick recovery time gives users a good supply of hot water1.
| Format | Capacities |
|---|---|
| Slimline | 180L, 210L |
| Standard | 210L, 250L, 300L |
The cylinders are MELCloud enabled, which the manufacturer describes as allowing remote control from a single device in any location, and a diverter valve accessory is included in the package1. Mitsubishi Electric says the cylinders are engineered for integration with its Ecodan R32 heat pumps, that a high-capacity coil heat exchanger maximises heat transfer, and that they are suitable for both new build and retrofit homes1.
"We are always looking for new and innovative ways to make the deployment of heat pump cylinders easier, to improve efficiency and give peace of mind to households. With the holistic product design and ability for installers to utilise readily available components, we've achieved this and expect demand for the product to be high."
Robert Taylor, Senior Product Manager, led the team that designed and developed the range1. Prices, warranty terms, cylinder dimensions beyond capacity, and the date the range goes on sale have not been reported1.
Why it matters for households
A heat pump cylinder is the store of hot water that lets a home run its heating and its taps from the same air source unit, so the size and format of the cylinder decide how much hot water is on hand and how hard the heat pump has to work to replace it. A cylinder that is too large for the household's demand is heated more than necessary; one that is too small runs out. Mitsubishi Electric's stated aim of matching capacity to the home, rather than defaulting to the largest tank, is a direct claim about running costs1.
The slimline format at 180L and 210L is aimed at homes where a standard cylinder will not fit, which is a common constraint in retrofit properties where an old cylinder or a combi boiler is being replaced. The standard range extends to 300L for larger households1. Control through MELCloud places scheduling and monitoring of hot water in the same app as the rest of an Ecodan system, which matters where a household wants to shift water heating to cheaper periods, though the announcement does not set out any tariff or time-of-use functions1.
What happens next
No launch date for the range, no pricing and no availability details have been reported1. Mitsubishi Electric directs readers to a dedicated page for the Versatile cylinder range for further information1.
