Repair or Replace: Which Costs Less?
A repair is cheaper today, but not always cheaper over time. Here is how we advise customers.
A repair usually makes sense when
- The heater is relatively new
- The fault is a single replaceable part
- The tank itself is not leaking or corroded
Replacement usually makes sense when
- The tank is leaking or the water is rusty
- It is an older or discontinued model such as the JH series
- Repair costs are approaching the price of a new unit

Replacing an Old Joven JH Series Heater?
The Joven JH series has been discontinued and succeeded by the JSH series. If your JH heater is failing, use this guide to find its current replacement model, then let our technicians confirm the fit on site.
Joven JH Series
Produced from 2011 to 2021. Units still in use are now 5 or more years old, and parts are becoming harder to source.
Joven JSH Series
The current Joven storage heater range from 2022 onwards, and the series we install as replacements.
Not sure which model you have?
Check the rating label on the side or underside of your heater. It shows the model name and tank capacity in litres. A clear photo of this label is all we need to recommend the right replacement.
JH to JSH Replacement Models
| Your Old Model | Replacement Model | Capacity | Suitable For | Fit |
|---|---|---|---|---|
| Joven JH 25 | Joven JSH 25 | 25 litres | Single bathroom, 2–3 users | Direct equivalent |
| Joven JH 35 | Joven JSH 35 | 35 litres | Bathroom shared by 3–4 users | Direct equivalent |
| Other JH models | Recommended on assessment | Based on usage | Larger households or multiple bathrooms | Check on site |
Every replacement is confirmed on site. Mounting position, piping and electrical connection are checked before installation, as older installations can differ from the current standard.

We will identify your Joven model and recommend the right replacement.

FAQ
No.
From 1 April 2018, only a PUB Licensed Plumber can carry out a storage heater replacement.
No need.
Replacing with an exact same model does not ensure better fitment nor does it result in lower replacement cost.
Many of the existing heater installations DO NOT comply with PUB code especially the older ones.
Our Licensed Plumber will require to redo a whole new pipe layout, add safety devices and fittings to comply with the Code of Practice for Water Services SS636-2018 (formerly CP 48).
Yes.
For shower and basin use, choosing a 23 – 30 litres tank will be more than enough for a single bathroom.
There will be a need for an additional cut-out to the false ceiling usually about 900x1000mm and reinstate after having completed the replacement.
The ceiling shall look the same like before.
If the heater is under 5 years old, it may be feasible to replace the parts however no one is sure until an onsite assessment is made. Sometimes the thermostat may also require changing which may add up to half the cost of a new heater.
If the heater is older, the tank may have corroded badly that the heating element cannot be removed.
Not necessarily.
Firstly, the brands that have models constructed of stainless steel does not provide a longer warranty
Having a stainless-steel inner tank:
- does not stop the heating element from failing
- does not stop the water leaking from the heating element screw thread causing short circuit
