Rinnai High-Efficiency Hybrid Water Heaters: LowER On-Site Emissions AND Meet Peak Demand at West Country Hotel

A West country hotel has just completed the installation of multiple Rinnai blends ready 20% continuous flow water heaters and bespoke Rinnai storage vessels. The Hybrid instantaneous and storage system has been designed to optimise gas usage and satisfy peak demand without wasteful storage oversizing.

The Hydrogen blends ready and BioLPG ready water heaters offer over 2000 lph (litre per hour) of temperature accurate hot water, rapidly replenishing the bespoke hot water vessel to ensure user comfort and satisfaction.

 

The Rinnai N Series continuous flow hot water heater range offers a more compact, enhanced combustion design that allows for easier installation, superior operational performance as well as ease of serviceability.

 

The Rinnai Sensei N Series is the first ever continuous flow hot water heating unit manufactured with stainless steel heat exchangers to be available in the UK – this gives an extended working life at optimum performance to each of the four models in the range. Added to this are the market leading extended warranties of up to 12 years in commercial environments, which accompany the hydrogen Blend-ready and Bio-LPG ready instantaneous water heaters.

 

The four N Series models are:

  • N1600i giving 954 litres per hour (at 50 degrees rise)
  • N1600e (external) also giving 954 litres per hour (at 50 degrees rise).
  • N1300i giving 775 litres per hour and
  • N1300e also giving 775 litres per hours of temperature controlled hot water at 50 degrees.

 

All the range is also low-NOx (Less than 26ppm meaning they gain additional points under BREEAM) and the futureproofed continuous flow water heater utilises Rinnai’s patented advanced burner technology with a 13-1 turn down ratio – the largest on the market combined with 96% efficiency rating. Integral controls on the units enable the water heater to achieve high efficiencies because of advanced burner control and high modulation ranges.

 

This wide range of modulation means that energy usage is completely optimised as the water heater through smart inbuilt controls will only heat the water to the temperature required thus preserving energy.

 

Rinnai also offers a full range of unvented and indirect storage cylinders – with capacities from 80 -200L.

Rinnai’s H3 range of products include domestic and commercial heat pumps that offer immediate property decarbonisation. Rinnai is determined to provide UK customers with cost effective low carbon solutions towards domestic and commercial hot water and building heating provision.

RINNAI TO INTRODUCE NEW E-SERIES

Rinnai is introducing the updated Rinnai E-Series early in 2025 with the 17CE Condensing External Water Heater. This upgrade ensures UK customers can benefit from the latest advancements in hot water heating technology.

Each unit is designed to reduce customer costs and provide continuous hot and clean water upon demand. The gas-fired water heaters are lightweight so there is no need for heavy lifting gear. The continuous flow water heaters are powerful yet diminutive with a max flowrate of twenty litres per min making them an ideal water heating solution where space is limited.

Inclusion of microprocessors enables the customer to pre-set water temperature delivered accurately to +1 / -1 degree of the set point helping eradicate legionella proliferation and delivery temperature inaccuracies that can create discomfort or scalding.

Rinnai’s continuous flow hot water systems will only use the required amount of energy to increase water temperature whilst supplying multiple litres of clean hot water. Continuous flow systems do not require energy consumption whilst not in use, meaning that the customer does not pay any costs when the system is not operational.

Both models – the 17CE are an ideal solution for glamping sites, leisure facilities, festival ablutions, small commercial outlets and where there is a requirement for cost effective and durable condensing water heaters.

The 17CE model weighs just 18kg and the unit is compact ensuring easy installation that requires far less space than alternative systems. The range of temperature is between 37 and 65 degrees Celsius, whilst hot water delivery capacity is twenty litres per minute. Gross efficiency is measured at 93%. Further additions include direct electronic ignition and frost protection.

The 17CE condensing water heater is a Bio-LPG ready water heater and the Natural gas continuous flow water heater is I2HY20 ready for Hydrogen blends of 20%. The range of temperature is between 37 and 65 degrees Celsius. Hot water delivery capacity is seventeen litres per minute.

Rinnai understands the UK customer requirement for cost effective and robust appliances that consistently deliver clean hot water and heating to domestic and commercial buildings across the UK. Rinnai are committed to offering UK customers low cost and practical solutions that cover all energy options.

RINNAI WARMS UP THE BONNY BANKS LOCH LOMOND

  

RINNAI WARMS UP THE BONNY BANKS OF HOLIDAY LODGES ON LOCH LOMOND WITH OFF-GRID LPG CONTINUOUS FLOW HOT WATER HEATING UNITS

 

Rinnai 1600e continuous flow water heaters, powered by LPG, have been installed in accommodation units at an off-grid holiday park on the banks of Scotland’s Loch Lomond, the UK’s biggest body of freshwater at just over 36 kilometres long.

 

The Loch Lomond & Trossachs area is also a highly popular National Park – 1,865 sq. km (720 sq. miles) – and has a boundary length of 350km (220miles). Just over 50% of Scotland’s population lives within an hour’s drive of this National Park

 

The site, towards the southern end of the loch, is popular all-year round, as it is just 40 minutes from Glasgow. The site has a selection of lodges and chalets, many with outdoor hot tubs, accommodating up to 10 people per each unit. There is a leisure centre, swimming pool, restaurants and cafes plus communal areas used for concerts, especially tribute acts.

 

The Rinnai LPG water heaters are powered by LPG but can work just as efficiently on BioLPG – a lower carbon intensive alternative source of fuel. LPG is one of the lowest carbon emitting sources of fuel for the 15% of UK businesses and domiciles that function off-grid. Bio-LPG could be one of the replacements for LPG in the future meaning that off-grid sites can “drop-in” lower carbon fuels of the future and Rinnai continuous flow water heaters will be ready, thus futureproofing their hot water heating provisions.

 

BioLPG consists of renewable materials derived from a diverse mix of sustainable biological feedstocks and processes. Supported through cleaner sourced chemical ingredients BioLPG provides huge benefits in carbon reductions and air quality, compared to traditional off-grid fuels such as heating oil.

 

Further alternative fuel sources such as renewable biofuel Dimethyl ether (DME) can also be employed by Rinnai continuous flow water heaters. Renewable DME is like LPG. It is a molecule-based fuel that can be produced through a wide range of renewable feedstocks which allows for quick and long-term sustainable production.

 

DME combusts cleanly and releases no “soot” emissions. Dimethyl ether has many fuel properties that make it easily used in sites and appliances using heating oil. It has a remarkably high cetane number, which is a measure of the fuel’s ignitibility in compression ignition engines. The energy efficiency and power ratings of DME and heating oil engines are virtually the same. R DME is safe and reduces greenhouse gas emissions by up to 85% better improving local air quality.

Rinnai is pioneering product development to support the green fuels of the future so that
LPG water heaters and boilers today are ready for a greener tomorrow.

Rinnai A-rated Infinity range for a low NOx infinite supply of safe hot water

Available from leading manufacturer Rinnai is claimed to be the most energy efficient, low NOx and cost-effective range of A-rated water heaters across a range of load profiles compared with any other gas fired continuous flow water heaters on the UK market.

RINNAI’S HEAVY-DUTY CONDENSING (HDC) INFINITY MODELS

The Infinity HDC1600i, tested to below 20 ppm NOx, produces the lowest emissions on the market, with 107% net thermal efficiencies. The newly developed unit with down-firing burner allows increased efficiency.

The established award-winning condensing HDC1200 internal and external models show an impressive energy performance of 107% net thermal efficiency while the larger Rinnai HDC1500 internal and external models turn in 105% net thermal efficiency.

The Rinnai Infinity Low NOx HD55i internal water heater is a room sealed, wall hung, LPG or natural gas fired continuous flow water heater. The Infinity Low NOx 55i is capable of supplying in excess of 980 litres at 50º rise per hour. Up to 25 units can be cascaded to satisfy any specification.

RINNAI SOLO

The Infinity Solo condensing, low NOx condensing water heater, is the first Rinnai product for the UK to combine the advanced technology of its wall mounted continuous flow water heaters with a stainless-steel storage cylinder in one compact unit.

RINNAI INFINITY PLUS

The Infinity Plus solution brings together multiple units of the company’s award-winning low NOx water heaters into single, easily manoeuvrable modules. All pre-assembled on ready fixed racks designed to fit through standard door frames.

Rinnai Solo for low NOx continuous flow on demand hot water……but with a store….

Rinnai Infinity Solo condensing and low NOx water heater is said to be the first of its kind in the UK to combine the advanced technology of low NOx wall mounted continuous flow water heaters with a stainless steel storage cylinder, all in one compact footprint.

The design parameters of this product allow specifiers, designers, installers and engineers to benefit from unique Rinnai technology in applications it was once not previously possible. For instance, the Infinity Solo features both 35kW and 54kW sized appliances, ensuring sites with a smaller gas meter can readily use this technology. The larger Infinity Solo model will also act as a high-efficiency alternative to gas fired storage appliances that exist in today’s market.

The cylinder is stainless steel and this reduces the weight compared to glass lined models, and it makes transportation, handling and installation a lot easier. As well as the difference in weight, the cylinders also have extremely low heat loss figures (as low as 1.41kW/h day), so the user pays less to maintain the heat within the tank.

Another benefit of the Infinity Solo with stainless steel cylinder is that the life expectancy of the material is far greater than that of a glass-lined equivalent as glass suffers from thermal shock causing it to crack after a period of time.

The Infinity Solo range is also renewables compatible and supplied pre-fitted with a coil, meaning that the primary energy source will always be from renewable gains and the complementary Rinnai water heater will only apply the precise amount of gas to boost the difference in temperature.

Rinnai manufactures the energy efficient Infinity range of low NOx gas fired continuous flow water heaters and space heaters. The Infinity brand carries the widest range of condensing water heaters on the market today with the most impressive efficiencies in operation, leading the field in technological innovation.
