VARMINPOOL V35 Ultra Pool Heat Pump (140K BTU, Heat & Cool)
For the very biggest pools — heats AND cools, up to 42,000 gal — A 140,000 BTU reversible (heat AND cool) inverter unit for in-ground pools up to 42,000 gallons — the biggest-pool pick in the field, and one of the few this size that also cools. Titanium exchanger, rated saltwater-safe, WiFi app and scheduling, and quiet at 47 dB. It's from VARMINPOOL, the value brand owners keep crediting with support you can actually reach (even a 1★ reviewer noted 'customer service was nice'). The catches: the 4.5★/198 base is pooled across VARMINPOOL's whole size ladder — many of those reviewers are running far smaller units — so read it line-wide, not V35-specific; there's no formal warranty; and the recurring reliability complaint is the unit freezing up or the display faulting.

Pros
- The biggest coverage in the field — up to 42,000 gal, for a large residential or light-commercial pool
- Reversible — heats in spring, cools the pool in summer; titanium exchanger, rated saltwater-safe
- The support owners actually reach (VARMINPOOL's responsiveness is a recurring theme, even in critical reviews)
- WiFi app with scheduling; 47 dB quiet
Cons
- The 85-rating base is pooled across VARMINPOOL's whole size ladder (visible reviewers run 6,000-gal / 30K-BTU units) — a line-wide score, not V35-specific
- No warranty in writing — you're trusting the brand's support track record
- The recurring reliability complaint is freeze-up / display faults; owners note support responds, but it's the honest catch
- The peak-COP figures on the listing are lab numbers — expect a real seasonal COP around 5–6
Freezing up with the front display dead — a real reliability catch, though owners consistently describe VARMINPOOL support as responsive.
