Hitachi Warranty Registration 7 Year

Underfloor Heating

If you are looking for an underfloor design which we guarantee will have the heat pump at the centre of the system design, 
instead of as an add on, come and talk to us at Freedom HP.

All Hitachi heat pumps can now be registered for a 7-year parts warranty, covering only the Hitachi components. Any labour charges 
for replacing faulty parts are not covered. The Hitachi warranty does not cover, radiators, cylinders, UFH, valves, pumps etc. It is the 
role of the installer to offer a warranty to the end user covering the heating system including the heat pump. Your installer may offer 
you their own full parts labour and call out warranty as part of their maintenance agreement, but you need to discuss this with the 
installer / maintenance company. The warranty will be held by the end user at the address the unit is installed. It is important that 
a qualified engineer services the unit annually to maintain the warranty . It does not have to be the installer who does this, we can 
recommend engineers to do this if the installer does not want to do this work.

Your unit is not automatically registered for warranty, your installer needs to fill in a form Online at 

www.freedomhp.co.uk.

 

Once this is done a certificate and a maintenance book will be emailed to the applicant, please make sure you have a copy of this 
certificate, and proof of maintenance. Hitachi may ask for this when a warranty claim is made.

Pipe

 

We supply a high quality 16x2mm 
multilayer pipe, consisting of 5 layers of 
polyethylene, adhesive and aluminium. 
Typically rated at 95°C at 10bar, this 
strong flexible pipe is well suited to 
underfloor heating, and is manufactured 
within the EU.

Controls

At Freedom we provide a wide range of 
controls manufactured by leading brands 
such as Heatmiser, Danfoss and Reliance. 
On offer are basic dial thermostats to 
the latest digital phone app controlled 
products.

Manifolds

Our brass manifolds are made in 
Germany, and are supplied to us by Watts 
Industries. This premium product has 
individual flow meters, isolation ball 
valves, and is fitted with an auto air vent 
and pressure gauge to aid testing.

Plate Systems

Our plate system is generally used for a suspended floor. Insulation should be fixed 
flush with the top of the existing joists to prevent downward heat loss. Battens are 
fixed at 400mm centres at 90° to the existing joists. Aluminium trays are then laid 
and stapled into position and the underfloor heating pipe is pressed into the grooves 
within the trays.

The pipe warms the trays and the heat is spread across the floor. Chipboard or 
plywood can then be laid and fixed to the battens.

Overlay Systems

Overlay panels provide many advantages over other insulation products when used 
with warm water underfloor heating systems.

Our panel dimensions are 1250mm in length by 350mm in width and either 20mm or 
25mm high.

Screed Systems

A Screed System is where the underfloor heating pipes are incorporated within 
the solid floor structure. Staples, interlocking cliprail or castellation mats are 
fixed directly on to the floor insulation. At Freedom Heat Pumps, we can provide 
everything from staples to cliprail through to castellation mats in order to suit your 
project.

Quotations are provided without obligation, and a fully insured BS1264 compliant AutoCAD pipe layout can be prepared prior to 
delivery and installation. This affords the client an opportunity to approve our suggestions prior to final acceptance. 

Do you have a project which you would like us to provide a competitive underfloor heating quotation for?  

If so, please email [email protected] or call 02380 274 833
