I bought 25 litre jaguar water heater 2 years ago and I was given a 7 years warranty on the product. I was ok as its not a complex machine and how hard it could be for two rods to heat up water.
The water heater was mounted and on the same day installation was done and I was happy with it for only 3 days as on the third day I turned it on and the indicator light turned on for power for 40 minutes I waited and drained water but it didn't came out and the water was still ice cold and I was highly disappointed with this fact.
I called support they said it's fused and will cost me to repair I was shocked and only its been 3 days and I was paying for repairs and warranty will cover half.
After that it lasted only 3 months during winters and again repairs and same for every season.After such experience I can not at all recommend it. So no from my side don't buy.
