Rinnai offers free site audit of hot water system energy costs

19 July 2022

Rinnai is offering free audits of total energy costs related to hot water systems on all sites. The audits are specifically aimed at maximising hot water delivery efficiencies thus making significant savings on fuel costs to the end-users.

Maximising efficiencies on site could result in fuel cost savings of up to 30% on current energy prices. Rinnai continuous flow technology means that hot water is heated only when required – energy costs stop immediately once the tap is not in manual use.

Total capital expenditure and carbon savings are to be included in the audit for the final Whole of Life calculation. The audit measures all data from individual and multiple sites concerning hot water use and presents a full and detailed report.

“This is our response to the tightening squeeze on costs that all businesses, commercial sites and homes are currently facing. We have a range of products which include gas fired solutions, hydrogen-20% blends ready, BioLPG and solar to electric heat pumps as part of our H3 initiative of ‘Hydrogen, Hybrid & Heat Pumps’,”said Tony Gittings, managing director of Rinnai UK.

A site visit can be booked by either calling 0300 373 0660 or visiting www.rinnai-uk/contact-us/request

Just recently the company announced the global-first of 100% Hydrogen hot water heating technology. Current UK Rinnai product ranges - both domestic and commercial - are ‘hydrogen blends ready’ - meaning that units will accept the proposed 20% hydrogen/natural gas blend. Rinnai UK is one of the first manufacturers to display the I2HY20 gas category certificate for all its products.

Rinnai has also announced help in reducing the carbon footprints of all sites and applications with the introduction of the Rinnai Carbon Cost Comparison Form. This is available FREE of any charge on:


Gittings said: “Continuous flow hot water heating units and systems deliver proven reductions on working costs and quantifiable improvements in energy efficiency, as well as provision of temperature-controlled end-product whenever the need arises. The user pays for only fuel used 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.

“Our carbon calculation service however will compare our complete H3 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 units are UKCA certified, A-rated water efficiency, accessed through multiple fuel options and are available for purchase 24/7, 365 days a year. Any unit can be delivered to any UK site within 24 hours.
