Kāo—Kāore ngā pūnaha HRV (Heat Recovery Ventilation), inā koa ngā tauira a IGUICOO, e whakapiki i ngā pire whakamahana. Engari, ka whakaitihia e rātou, nā te kaha penapena pūngao ote whakapūngao whakaora wera. Nā te mea tēneite whakapūngao whakaora werae aro ana ki tētahi āhuatanga matua o te moumou: ina panaia e ngā pūwero tuku iho te hau tawhito, ka ngaro hoki te hau wera nui, ka kaha ake te mahi a tō pūnaha whakamahana.

Ka whakamahia e te HRV a IGUICOO ngā taputapu matataute whakapūngao whakaora werahangarau hei whakatika i tēnei. Ka hopukina e tana whakawhiti wera te 90% o te wera mai i te hau tawhito e puta atu ana, ka tukuna ki te hau hou o waho e tomo mai ana. Ko te tikanga o tēnei kua whakamahanahia te hau hou e tomo mai ana ki tō whare, nō reira kāore e hiahiatia kia nui rawa te mahi a tō pūnaha whakamahana kia mau tonu te pāmahana pai—ka whakaitihia te whakamahinga pūngao me te whakaiti i ngā pire whakamahana.

He rerekē ki te hauhautanga taketake e mimiti ana i te wera,te whakapūngao whakaora werae pupuri ana i te mahana i roto, me te tuku tonu i te hau hou. Nā IGUICOOte whakapūngao whakaora weraHe mea hanga kia whai hua: ahakoa e oma ana i te 24/7 (he mea nui mō te kounga pai o te hau), he iti noa te mana e whakamahia ana e ōna motuka iti-pūngao, he iti iho i te pūngao e penapenahia ana e tō pūnaha whakamahana.

Hei tauira, i te hotoke, he whare kāore hete whakapūngao whakaora weratērā pea ka ngaro te 30% o te hau wera mā roto i ngā pūwero. Mā te HRV a IGUICOO, ka tino heke taua ngaronga, i te meate whakapūngao whakaora weraka hangarua te mahana. I roto i te wā, ka nui ake ngā penapena i ngā pire whakamahana.

I roto i te poto, ka whakamahia e te HRV a IGUICOOte whakapūngao whakaora werahei whakaiti—kaua hei whakanui—i ngā utu whakamahana. He haumitanga atamai tēnei e pupuri ana i tō kāinga kia mahana, kia hou, kia pai hoki te tahua, nā te tohungatanga o IGUICOO ki te ponote whakapūngao whakaora werangā otinga.
