Rinnai\u2019s heavy-duty condensing range uses two heat exchangers to capture residual heat from flue gases to pre-heat incoming water, with the HDC1500i turning in 105% net efficiencies*. These figures add up to considerable on-going energy savings when compared with traditional gas fired stored water systems.<\/p>\n
With a Rinnai condensing unit, temperature is regulated to within +\/-1\u00baC via \u2018smart\u2019 internal controls without any variation of temperature at the outlet even when water is drawn off elsewhere. All models have full electronic ignition, no pilot light and operate on demand only, so there is no gas consumption when the unit is idle.<\/p>\n
The units are easily configured in a manifold arrangement, ensuring there will never be a shortfall of instant hot water whatever the demand.<\/p>\n
Rinnai, the UK\u2019s leading manufacturer of the ErP A-rated Infinity range of continuous flow condensing gas-fired water heaters, supplies the best energy efficient range of low-NoX water heating units currently on the market.<\/p>\n
Advanced condensing heat exchangers combined with innovative burner technology ensures that every cubic metre of gas is used to the maximum on HDC 1500i.<\/p>\n
Legionella proliferation is answered by Rinnai: the company has developed additional \u2018SMART\u2019 controls for secondary return DHW systems in the form of an advanced temperature control system which allows for safe running of water at 42\u00b0C core temperature during the day and 60\u00b0C at a time when the building is closed. By the time the building reopens, core temperature is 42\u00b0C for safe use.<\/p>\n
Another Rinnai innovation addresses an age-old industry problem with hot water delivery – lime scale build-up. The company\u2019s integrated scale control system is an innovative solution and comes in the form of an LC (lime check) code on the display of the controller.<\/p>\n
Almost all water-fed appliances, including plate heat exchangers, boilers and water heaters will accumulate scale deposits when used within hard water areas over time. Lime scale consists of calcium carbonate (calcite) with lesser amounts of other calcium salts such as the sulphate. Sometimes lime scale deposits contain corrosion debris and this scale build-up can affect the water heaters by reducing their efficiency and overall performance.\u00a0 Ultimately, ongoing use with hard water may shorten the lifespan of conventional water heating appliances and systems. To safeguard against this Rinnai units continually self-monitor for lime scale deposits around the heat exchanger. If a lime scale build up has being identified, a message is sent to the built-in interface panel on the front of the appliance.\u00a0 The message is displayed as \u2018LC\u2019, which alerts the end user that it is time to call a Rinnai service agent to perform a lime scale flush to clear the potentially harmful deposits.\u00a0 This avoids and eliminates the adverse effects associated with lime scale build up, including lower energy efficiencies and rapid product de-generation.<\/p>\n
Rinnai\u2019s HDC range offers condensing technology with up to 107% gross efficiency, ultra-low-Nox of less than 20 ppm, a widely expansive modulation range of 54kW-4kW and high flow rates of 37\/ltr\/min. Add to these benefits are the peace of mind of an extended warranty, a top A-rating exceeding the demands of\u00a0 eco-labelling legislation, the flexibility of external wall mounting and delivery to site with all relevant accessories and the knowledge that the HDC range is future-proofed against future regulatory and legislative changes.<\/p>\n

Rinnai has just completed the installation of two HDC1500i continuous flow hot water heating units at a busy laundrette serving businesses and the public in Stafford. Rinnai were chosen on the recommendation of another laundrette owner, in Lancashire, who praised the efficiency and major cost savings because of switching to cascaded continuous flow hot water units as they guarantee almost unlimited supplies of hot water at peak demand whilst savings on fuel costs.<\/p>\n","protected":false},"author":3,"featured_media":9730,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"jetpack_post_was_ever_published":false,"_jetpack_newsletter_access":"","jetpack_publicize_message":"","jetpack_is_tweetstorm":false,"jetpack_publicize_feature_enabled":true,"jetpack_social_post_already_shared":false,"jetpack_social_options":{"image_generator_settings":{"template":"highway","enabled":false}}},"categories":[4],"tags":[],"jetpack_publicize_connections":[],"yoast_head":"\n
