Good water heater for under sink. Would have liked it to be a bit warmer but does the job.

Excellent service from the Heater Shop. Order placed and item received within 48 hours. Would have been next day but the delivery person said he didn't have time to deliver when he was supposed to. No fault of the Heater Shop.

Thank you so much for this great 5-star review. We really appreciate your business and helping to share the word about Heater Shop.

Installed and operating although the fibre washer on the hot connector had to be replaced with a rubber washer. It was bought to replace one from another manufacturer which repeatedly failed (triac failure) after about 12 months use - 4 times in 4 years. It remains to be seen how reliable this one is.

Very prompt, efficient delivery

Thank you for this positive review on our delivery service. We highly appreciate this.
