ʻIke ʻia nā ʻōpala wela kumu ea ʻo ia kekahi o nā ala ʻoi loa ka ikaika o ka ikehu i ka home. Ma muli o ka Coefficient of Performance (CoP) o nā puna wela ea, hiki iā lākou ke hoʻokō i nā helu kūpono o 200-350%, no ka mea, ʻoi aku ka nui o ka wela a lākou e hana ai ma mua o ka hoʻokomo uila i kēlā me kēia ʻāpana o ka ikehu. Ke hoʻohālikelike ʻia me ka paila, ʻoi aku ka maikaʻi o nā pamu wela a hiki i 350% (3 a 4 mau manawa) ʻoi aku ka maikaʻi, no ka mea, ʻoi aku ka liʻiliʻi o ka ikehu e pili ana i ka wela a lākou e hoʻohana ai i ka home.
ʻO ka nui o ka ikehu e pono ai ka paila wela e holo ma muli o kekahi mau kumu, e like me ke aniau a me ke kau, ke ʻano o ka ductwork a me ka insulation a me ke kūlana a me ka nui o ka waiwai.
I ka helu ʻana i ka nui o ka uila e pono ai ʻoe e holo i kahi puna wela ea, pono ʻoe e noʻonoʻo i kāna CoP. ʻO ke kiʻekiʻe, ʻoi aku ka maikaʻi, no ka mea, e hoʻohana ʻoe i ka uila liʻiliʻi e hoʻohua i ka nui o ka wela āu e koi ai.
E nānā kākou i kekahi laʻana…
No kēlā me kēia 1 kWh o ka uila, hiki i kahi puna wela ea ke hana i 3kWh o ka wela. ʻO ka awelika noi makahiki no ka hapa nui o nā hale UK ma kahi o 12,000 kWh.
12,000 kWh (koi wela) / 3kWh (wela i hana ʻia i kēlā me kēia ʻāpana uila) = 4,000 kWh o ka uila.
Inā kūʻai ʻia kāu uila ma ka £0.15 i hoʻokahi ʻāpana¹, e uku ʻia iā ʻoe he £600 no ka holo ʻana i kāu puna wela.
