Our quality renowned GrippaMAX cleaning systems are now available with full hot water integration. We can also offer retro upgrade kits for customers with existing systems. The HydroHeat 9.1kw heater system is manufactured in house by GrippaTank and uses industry leading boiler technology. 

Cleaning with hot water is both easier and more effective - make the change today!

The HydroHeat 9.1kw boiler has the following benefits:

  • Cleaning with hot water cuts into dirt and grime far quicker than using cold water, so buying a hot water system will speed up your work. Many of our customers report a 30% saving on time.
  • Energy efficient 9.1kw diesel heater system - uses approximately 0.9 litre per hour of use on maximum output and only 7 - 8 amps of electric.
  • Fully adjustable temperature - capable of heating water upto 60c at heater point. Temperature outputs at brushes will vary depending on the length of hose pulled out from the van, and the temperature on the ground.
  • Temperature can be adjusted per operative
  • Frost stat - system will kick into life when 2c is read and circulate water through plumbing and hose reels and then back to tank to prevent freezing occuring overnight.
  • Unlike many systems on the market that use cheap plastic connections, the HydroHeat system comes with stainless steel plumbing fittings as standard.
  • System is recommended to run with 2 x 110ah batteries along with our SmartCharge split relay kit.
  • We can provide bespoke cabinet designs in order to fit in with your existing system.
  • Dimensions of the 3 options as follows:
  • (a) GrippaMAX Delivery Heater cabinet: W 980mm x H 635mm x D 160mm
  • (b) GrippaMAX Heater cabinet for RODI: W 980mm x H 580mm x D 166mm 
  • (c) Retro Fit Heater cabinet for other systems: W 585mm x H 895mm x D 265mm
  • We can make bespoke cabinets to fit your existing vehicles.
  • Three years manufacturers fault warranty as standard, when serviced annually.

See examples of systems recently supplied on our feedback page.

Fitting Time:

  • As part of a complete system supply: 1 Week
  • A retro fit to an existing system: 1 Week

NB:- Our HydroHeat diesel heater systems use heat on demand technology which require a recommended flow rate to achieve optimum temperatures from the output of the heater.

The HydroHeat system requires servicing every 12 months. It is imperative that services are kept up to date, as failure to do so will invalidate the warranty. 

What our Customers say:

"The hot water system is excellent, well thought out. Having used it for 6 months with my VW caddy maxi, the whole system is well designed and simple to use, effective and very efficient. Initially, the cost of the speed liner, 400 litre grippatank and hot water tank put me off, however, worth the investment, once you start working with the system, the cost justifies itself. Having the hot water is not only useful through the winter but knocks off spider spots nicely, cleans superbly. Somehow I seem to be earning a lot more money by the end of each day, perhaps saving 10 minutes per hour." - S.P, Southampton.

What a difference the hot water makes

Review by M.M - Scotland on 23/12/2019

Hi, Did a few first cleans today and what a difference the hot water makes especially when you tell the customers. Then a quick getaway winding the hose on with electric ways. Definitely the way forward when cleaning windows or pvc. Cheers m

Customer service is outstanding and sets them miles apart

Review by S&E Cleaning Solutions LTD on 25/01/2017

After having a heater installed by another company and really struggling with poor communication & customer service,I was looking for a new company to fit a heater to one of our vans.

After looking online we found GrippaTank through the Gardiner pole systems site ( who provide all our poles and parts ).

After discussing what I was after, Oliver put me a quote together for the heater to Retrofit my existing system.

Nothing was to much trouble for Oliver and his team, I even had a custom Aluminum race fuel tank instead of piping into the vehicle fuel tank which was a personal choice.

The system was installed at the depot ( 2 1/2 hrs away ) I was even given a lift to the train station by Paul the engineer who answered every single question a had with great knowledge and professionalism.

There customer service is outstanding and sets them miles apart from any competition, and the system itself is amazing and kept another van out working during These cold months.

If you are looking at a heated system look no further. You will not find a better system or company, trust me I've tried them.

Many thanks
S&E Cleaning Solutions LTD.
