Rinnai continues to make additions and innovations in both products and services to complement its new H3 range of Hydrogen, Hybrid & Heat Pumps ranges.

In helping reduce the carbon footprints and fuel costs of all sites and applications Rinnai is introducing an online Carbon Cost Comparison Form, which is available

FREE of any charge – CLICK HERE


The Rinnai H3 Carbon Cost Comparison Form offers a free appraisal of a site’s current heating & hot water delivery system, along with recommendations for reducing the carbon load and associated operational fuel costs. System designers, consultants, contractors and FM operators can simply visit the Rinnai website, complete the form and hit the ‘Submit’ prompt. Rinnai then makes a thorough analysis and returns all data direct to the user. Hard copies of the form are available on request.

This information gathering is very brief; current model and system, maximum gross input power, quantity needed, type of outlet (e.g., shower, washing basin) and how many peak demands in a day. Collected data is then passed to the Rinnai Technical team which calculates emissions and savings which can be made on both carbon load and fuel costs.

The Rinnai Carbon Cost Comparison Form is located as part of the Rinnai suite of innovative digital touchpoints (Carbon cost comparison form :: Rinnai UK (rinnai-uk.co.uk). These pages are designed to make customer decision making fluid and specific.

Says Chris Goggin for Rinnai, ‘H3 offers proven reductions on working costs and quantifiable improvements in energy efficiency, as well as provision of a temperature-controlled end product whenever the need arises. For example, the user pays for only fuel used on a continuous flow system to heat the water at point of use – NOT when on standby as in stored tank holding systems creating cost effective and carbon reducing solutions for systems on the gas grid. This H3 calculation service will compare our complete array of Hydrogen blend ready water heaters, Hybrid solar and heat pump systems, and stand-alone heat pump solutions, providing our customers with market leading low carbon solutions.

Rinnai offer comprehensive training courses and technical support in all aspects of the water heating industry. More information is on Rinnai’s website and its “Help Me Choose” webpage.

Rinnai now offers H1, H2 & H3 solutions to the energy question in the cost-of-living squeeze.

H1 – Hydrogen blends ready, renewable liquid fuel ready and electric water heating equipment.

H2 – Hybrid hot water systems – Including heat pumps, solar thermal, solar PV and electric.
